Excel Formula with OFFSET Fails When Copied to Different Sheet - excel

I've been struggling with this longer than I care to admit, but I have a fairly simple OFFSET function call which works on one sheet, but if I copy it to a different sheet it gives a #VALUE error.
On a sheet named "Deliverable" I have this formula in a cell:
=OFFSET(Deliverable!$B$72,1,0,,3)
and it works fine.
If I go to any other sheet and use the same exact formula, or use it in the Name Manager, it gives a #VALUE error.
If I leave off the final parameter indicated the number of columns I want, it does work:
=OFFSET(Deliverable!$B$72,1,0)
but of course isn't giving me the range I need.
Any idea what's going on with this?
I'm using Excel 2016 on Windows 7.
-- Updated Info --
In a nutshell, my spreadsheet has two cells which I'm using as dropdown lists, where the 2nd cell's list feeds off the selection in the first. The data they are based on has this format:
OptionA A B C D
OptionB A B
OptionC D E F
So the first dropdown uses a simple Data Validation source pointing to the column with OptionA, OptionB, etc. Once that's chosen, the second dropdown list should contain the appropriate options for the one selected. So if OptionB is selected, then the 2nd dropdown list should show A and B.
When I initially wrote this, the data validation source was just a simple VLOOKUP entry, but the lists often had blanks since the number of options varies for each entry. Wanting to fix it up a bit, I ended up with this formula:
=OFFSET(Deliverable!B72,Deliverable!B87,0,1,COUNTA(OFFSET(Deliverable!B72,Deliverable!B87,0,1,5)))
There won't be any more than 5 options, and there are no empty cells in the middle of the data to filter out.
In one spreadsheet I have I used this as a named range definition, then specified the named range for the cells data validation source and it worked. In this other spreadsheet however, it gave me the error described earlier.
However, it looks like when I enter the statement directly into the data validation source field and not in the name manager, it works as expected.
Am I taking the totally wrong approach?

What is it that you want this formula to do? As written, it is returning a block of three horizontal cells. The #VALUE error is Excel's way of telling you "Hey, you're trying to return three cells, but I can't fit them all in the one cell that you are calling this formula from".
The reason you see a result in some places and not others is because of something called Implicit Intersection. Give it a spin on Google. But basically, it just returns whichever one of those three results corresponds to the column that the formula is entered into. If you copy that exact same formula to say row F you will see that it returns a #VALUE error there, because it doesn't know what cell it should return given the column you're calling it from doesn't match any of the cells it is returning. The fact that you don't know this indicates that the formula you're using doesn't in fact do what you think it does.
--UPDATE --
Okay, following your further clarificaiton it seems that you're talking about Cascading Dropdowns aka Dynamic Dropdowns. Lots of info on Google about how to set these up, but you may be interested in an approach I blogged about sometime back that not only provides this functionality, but also ensures that someone can't later on go and change the 'upstream' dropdown without first clearing the 'downstream' one should they want to make a change.
Note that those links talk about a slightly complicated method compared to others, but the method has it's advantages in that it also handles more levels than two, and your DV lists are easily maintained as they live in an Excel Table.

This sounds like an array equation. Try hitting Ctrl+Shift+Enter in the other sheets to validate it as an array equation.
Whenever you need to reference ranges instead of single cells, Excel needs to know that you are working with arrays.

Dropdown list with a conditional statement

I have some materials in column B, a few among these are in a Table definition called Material_List. In D49 I am trying to write a conditional statement such that, if the data in B49 already exists in the table definition, then print the header name or else INDIRECT($49). C49 has the independent dropdown list and D49 will be the dependent.
In D49 I have used the following formula within the Data-->Data Validation-->Source=
=IF(MAX((ISNUMBER(MATCH(Material_List;$B49;0))*COLUMN(Material_List)))=0;
INDIRECT($C49);
INDEX(Material_List[#Headers];1;MAX((ISNUMBER(MATCH(Material_List;$B49;0))*
COLUMN(Material_List))))))
with Allow=List. But it says Error "There is a problem with this formula"
When typed the following formula in cell D50 directly, it works well but obviously without dropdown.
=IF(MAX((ISNUMBER(MATCH(Material_List;$B50;0))*COLUMN(Material_List)))=0;
INDIRECT($C50);
INDEX(Material_List[#Headers];1;MAX((ISNUMBER(MATCH(Material_List;$B50;0))*
COLUMN(Material_List))))))
I am trying to build a dropdown list based on the mentioned criteria. could anyone please tell what is wrong with my formula?
I think the main issue with your formula is that you cannot use table references in the data validation.
Don't ask me why. I think it is just an outstanding Excel bug which hasn't been fixed yet. Please see this link for further info: https://exceloffthegrid.com/using-an-excel-table-within-a-data-validation-list/
The best way I have found to work around this is to create a named range which refers to the table references you need ("Material_List" and "Material_List[#Headers]" in your case). Then you can use those named ranges in your data validation instead of the table references directly.
However, I think there are also other issues with your formula. For example, this part:
MATCH(Material_List;$B50;0)
Normally a MATCH would be in the format of:
MATCH(<single value to look for>, <range to look in>, 0)
You appear to have that reversed, meaning that it should always return a #VALUE! error.
Also, I don't think you can use match on a 2D array, so if your "Material_List" table is more than a single column, that would also cause it to return a #VALUE! error.
UPDATE:
The way I would tackle dependent dropdowns would be as follows.
I would create a "Material_List" table similar to below (could be on a hidden sheet):
Then I would create 3 named ranges.
One for the table body range, called "MaterialList_TblRange":
=Material_List
One for the table header range, called "MaterialList_TblHeaderRange":
=Material_List[#Headers]
And one to refer to the dependant dropdown options, called "DropDownOptions" (this is by far the most complicated part):
=INDEX(MaterialList_TblRange,1,MATCH(Sheet1!$B23,MaterialList_TblHeaderRange,0)):INDEX(MaterialList_TblRange,COUNTA(INDEX(MaterialList_TblRange,1,MATCH(Sheet1!$B23,MaterialList_TblHeaderRange,0)):INDEX(MaterialList_TblRange,ROWS(MaterialList_TblRange),MATCH(Sheet1!$B23,MaterialList_TblHeaderRange,0))),MATCH(Sheet1!$B23,MaterialList_TblHeaderRange,0))
I will explain what this is doing in a moment.
The last step is to set up the data validation where we want our lists.
Where we want the master lists to appear, we can simply enter:
=MaterialList_TblHeaderRange
And the defendant dropdown validation can be entered as:
=DropDownOptions
This is the result:
Now back to the long "DropDownOptions" named range formula...
Basically, we use INDEX:INDEX to select the first/last cell in the range we want to use in out dropdown.
The first INDEX:
=INDEX(MaterialList_TblRange,1,MATCH(Sheet1!$B23,MaterialList_TblHeaderRange,0))
Simply selects the first cell from the column whose header matches the selection in our first dropdown.
The second index does the same, except that instead of selecting the first cell in the column, it counts the number of cells that contain text and uses that as the last cell in the range.
This does mean that we mustn't have any gaps in this table, otherwise an option might be missed off the end.
I hope this makes sense.

Can these formulas be simplified? Why does INDIRECT function seem to not work inside an ISBLANK test within a MATCH formula?

Summary
I need an array formula that takes a row of data of certain length from Sheet1. For that row, in each column that is not blank, I need to grab the Sheet1 header value for that column and display that data in a continuous row on Sheet2 (without any spaces in between the row's cells).
Background
I have a table of data (employees and industry certifications with expiration date being the table's cell data) on sheet 1, with a row for each employee the spreadsheet is tracking. The certifications are the columns.
We are using this information to link to ID Badge Printer software (Bodno Silver), where we are limited to linking columns of data to a particular textbox.
The problem lies in the fact that not everyone has every certification. The rows are peppered with blanks separating the certifications that each employee does have. While setting up the required text boxes in the badge software template, that each link to a specific column, I quickly realized that since not everyone has every certification if we used the data how it was we would have a bunch of strange looking blanks in between the listed certifications rather than a continuous list.
What I did
My solution to this (which I'm open to a better one if anyone knows of one, other than "use better software"), was to create a new sheet and array formulas that no one would use except for me and the id printer software. This sheet would have a similar data table that took the rows of data interspersed with blank cells between expiration dates, and put the matching column headers for cells that had a date in them into a continuous row of the same maximum length (eliminating the blank cells).
Essentially, this would allow me to circumvent the restrictions of the badge software and each textbox would be MatchedCert1, MatchedCert2, MatchedCert3, etc. up to the original maximum number of certifications.
Pictures are probably better than my words at explaining what I am going for:
Sheet1 (source)
Sheet2 (result)
The array formulas
I worked on this one for a while. What I thought would be a simple INDEX, MATCH, ISBLANK formula (that I could create using the appropriate relative and absolute cell linking) and then expand to the whole sheet turned into a witch hunt and me praying for forgiveness for my sins to all that may be holy. Also a lot of googling.... I realized quickly that this one may not be so simple after all.
Finally, I arrived at the following two array formulas in order to correctly show what I was going for:
First Column of training section
{=IFERROR(INDEX(Sheet1!$E$2:$P3,1,MATCH(FALSE,ISBLANK(Sheet1!E3:Q3),0)),"")}
(easy enough, right? I thought so...)
I felt good about this until I tried to think through what would be required to get the formula to be universal so that I could use it on the entire table.
I feel dirty just putting the following in public, but here goes...
Second column through last column array formula
{=IFNA(INDEX(INDIRECT(ADDRESS(ROW($E$2),(MATCH(E3,Sheet1!$2:$2,0)+1),1,1, "Sheet1")&":"&ADDRESS(ROW(E3),COLUMN($Q3),1)),1,MATCH(FALSE, ISBLANK(INDEX(INDIRECT("Sheet1!"&ADDRESS(ROW(E3),(MATCH(E3,Sheet1!$2:$2,0)+1),1)&":"&ADDRESS(ROW(E3),COLUMN($Q3),1)),0,0)), 0)),"")}
(please don't call the police...)
[ninja edit] While this array formula works for 2nd result column through the final column, it doesn't work if there's not a blank column following the result range. The actual spreadsheet has 4 different groups of certifications that run horizontally, but I was able to just add a blank column in the corresponding data from the other sheet easily enough, so I just let it go. I'd give somebody a nickle for the answer to why that's the case here too [/edit]
Results
The first array formula, and INDEX MATCH using ISBLANK is rather straightforward.
The biggest question for me here, and the thing that drove me absolutely nuts for a couple of days, is why the second array formula requires the additional INDEX function nested inside of the ISBLANK function.
While taking the function apart and experimenting I realized that if I have any INDIRECT reference inside a ISBLANK function, which is itself inside of a MATCH function, the result of the match was ALWAYS 1:
{=MATCH(FALSE,ISBLANK(INDIRECT("$E3:$Q3")), 0)}
The above ALWAYS returns 1, whereas if I put the range in explicitly, the function would work just fine. That wasn't an option for me, since I needed to dynamically return the starting position for the match using the previous cell's address.
However, adding an INDEX function (with a column and row value of 0) to encapsulate the INDIRECT function provides the correct answer. I figured this out just by trial and error.
Questions
Can someone with more knowledge please let me know what is causing this behavior?
As a broader question, given I am limited to using formulas (no VBA), I would also like to know if I'm going about this in the wrong way or if there is a much simpler way of accomplishing this without this behemoth of a formula?
I know this sheet will probably require maintenance in a year - good luck future self!
Put this in E3, Copy over and down
=IFERROR(INDEX(Sheet1!$2:$2,AGGREGATE(15,6,COLUMN(INDEX($E:$P,MATCH($C3,Sheet1!$C:$C,0),0))/(INDEX(Sheet1!$E:$P,MATCH($C3,Sheet1!$C:$C,0),0)<>""),COLUMN(A:A))),"")
As to why your formula is not working, it is too convoluted to parse. One note, unless the sheets is the variable, one should avoid INDIRECT as much as possible. INDEX can almost always be used in its place.
Both INDIRECT and ADDRESS are volatile functions. Volatile functions will re-calculate every time Excel re-calculates, leading to a lot of unnecessary computations.
Not a solution but to answer why you are seeing this behavior:
EDIT: PREVIOUS EXPLANATION WAS JUST PLAIN WRONG
This confused me so, I did a bit of investigation:
I think that your problem is actually coming from the ISBLANK function because it is intended to be used with single values, and cannot handle ranges. Any BLANKs which are returned by functions are only converted to numeric values (0), when the BLANK is returned to (or displayed on) the sheet. If the function is returning to another function, the BLANK value seems to be preserved.
EDIT: ADDING A SOLUTION WITHOUT ARRAY FORMULAS
This is probably more complex than using an array formula... but I strongly dislike them, so do all I can to remove them.
Firstly, I would add an index to your positions in the results sheet:
=IF(F$7>COUNTIFS($F3:$L3,"<>"),
"",
IF(
MINIFS(
$F$7:$L$7,$F$7:$L$7,
">" & IFNA(INDEX($F$7:$L$7,MATCH(E9,$F$2:$L$2,0)),0),
$F3:$L3,
"<>"
)=0,
"",
INDEX(
$F$2:$L$2,
MATCH(
MINIFS(
$F$7:$L$7,$F$7:$L$7,
">" & IFNA(INDEX($F$7:$L$7,MATCH(E9,$F$2:$L$2,0)),0),
$F3:$L3,
"<>"
),
$F$7:$L$7,
0
)
)
)
)
Basically, the formula looks at the cert in the previous cell, and looks for the next, minimum index, greater than that.

VLOOKUP and INDEX return #N/A when referencing another LOOKUP cell

I'm working on an Excel 2010 worksheet that uses a table that references a secondary table to generate a list of values.
More specifically, I have two tables: Table_Players and Table_ChallengeCalc. In Table_Players, I have the columns Players, Experience, and Level. I input the total number of points that a given player has under the experience table, and using this formula the level column tells me what level the player is:
Table_Players:
=LOOKUP(C6,
{-1;0;300;900;2700;6500;14000;23000;34000;48000;64000;85000;100000;120000;140000;165000;195000;225000;265000;305000;355000},{"0";"1";"2";"3";"4";"5";"6";"7";"8";"9";"10";"11";"12";"13";"14";"15";"16";"17";"18";"19";"20"})
Table_ChallengeCalc resides on a different sheet in the workbook, and references the Level value in Table_Players to pull a list of additional values from another table, Table_Difficulty.
Before I implemented the above lookup formula, I was just manually inputting the player's levels and in turn, the Table_ChallengeCalc was pulling the correct values for the remaining columns, using this to load the player's assigned level on Table_Players:
Table_ChallengeCalc:
=VLOOKUP([Players],Table_Players[Level],3,FALSE)
(Here's what it looks like when it works correctly):
However, as soon as I added the first LOOKUP value, the second VLOOKUP immediately became #N/A and in turn, so did all of the rest of the reference columns. If I remove the first lookup and manually enter the level again, the VLOOKUP immediately starts working again. I tried using a nested INDEX/MATCH statement, but it had the same results. As long as I'm using that first LOOKUP, Table_ChallengeCalc can't seem to pull the level value.
If I didn't know any better, it would seem to me that the workbook is trying to run the VLOOKUP simultaneously, if not immediately prior, the LOOKUP formula. Any ideas on how I can counter this, or is this one of those things where I've kind of hit the limitations of what an Excel workbook can do without additional software like VBA?
If I understand your issue correctly, then using the following formula should work for you:
=VLOOKUP([Players], Table_Players, 3, FALSE)
You currently have this in your table_array: Table_Players[Level], but your "[Level]" column is coming from the col_index_num: 3 in the formula, so you should not include this in your table array.

Excel drag handle auto-fill giving erroneous values (from cache/memory)

I use the auto-fill handle very often; both dragging and double-clicking. I need it, so I don't want to disable it in the options. However, I have certain situations where I'm just trying to copy down values to the next cells, and it appears Excel is using some type of memory/cache to auto-fill them with crazy values. I recognize the values; but there is no rhyme or reason as to why it's auto-filling them at this moment in time.
Example: There are no formulas in any of these cells and this is just a brand new sheet in Excel. I want to grab handle of cell B10 and copy it down to B14:
Now, I wish I could record a little clip of me copying this down so you can see it change the values live, but I promise you, this is what the values get changed to, and it has no relation to the values above it in the same column or anywhere in this sheet and there are zero formulas anywhere; just a simple table being populated:
What can I do to get this to copy the correct values? This has created errors in other tables where I didn't catch it populating the cells incorrectly in time.
My colleague has been suffering this exact problem and his solution is detailed below:
Go into Advanced Options and under General click on Edit Custom Lists button and you should find your values listed there. If so, you can delete them from this list and the problem should go away
Good luck!

Use INDEX/MATCH to select formula written as string, and enable it?

I have a pricelist, with currently 5 different categories of products. Each product will have to have two different prices. Depedning of the product and the type of price, the calculation will be different. Therefor I've used INDEX/MATCH to find the formula needed, from a table I created.
Below a screendump, and I wanted to attach the Excel fil, but canøt seem to work out how.
Question: HOW do I then "run" the formula I fetched? -I've tried different suggestions on using EVALUATION, but it doesn't seem to cut it? Also I've tried "Indirect' on the whole formula, without success.
I would like to avoid any VBA for this case.
Can anybody provide some insight?
You could but if I understand properly, the only thing changing in the formulas is the "muliplier" number, then it's better to lookup that number instead of the whole formula. The other method (which would use Evaluate etc) is not be considered "good practice" for a number of reasons.
EDIT:
I didn't see the 2nd varying value (since I was on the SO mobile app) but it's still not an issue since it would a target column. You could be thinking of the opposite: sometimes lookups based on multiple criteria can get complicated, but this a matter of more data, as opposed to adding criteria for the lookup.
VLookup would have been the simplest method, like G2 could have been:
=VLOOKUP(E2, $J$4:$L$8, 2, False)
...to return the second column of range J4:L8 where the first column equals E2. (Then for the next required column, same formula except with 3 instead of 2.)
Since I wasn't sure more columns could be added one day, I allowed for that by, instead of specifying "Column 2 or 3" etc, it finds the column dynamically by name. (So the multiplier/factor used in G2 will change if you change the title in G1 to the name of a different column existing in the target data chart.
For the sake of neatness as well as potential of additional columns like G & H, I moved the lookup table to a separate sheet. It can stay out of the way since you won't need to see or change it very often. (If the same chart was going to be referenced by many workbooks, you could even move it to a separate workbook and point all formulas at that, since it's always best to have one copy of identical data instead of many in different workbooks.
Also to assist with potential future changes (and just to be tidier), instead of referring to the target table range addresses (like "J4:L8" etc) I named two ranges:
the table of multiplier/factor data can be referred to by it's address, or by myMultipliers
the titles of the same table is also called myMultiplierTitles (used to match to the titles of column G & H on the original sheet.
Formula
After those changes, the lookup formula in G2 is:
=INDIRECT(VLOOKUP($E2,myMultipliers,MATCH(G$1,myMultiplierTitles,0),FALSE)&ROW())*VLOOKUP($E2,myMultipliers,MATCH(G$1,myMultiplierTitles,0)+1,FALSE)
INDIRECT returns the value of a cell that you refer to by name (text/string) as opposed to directly (as a range). For example:
=INDIRECT("A1")
returns the same as
=A1
...but with INDIRECT we can get the name from elsewhere (a cell, function or formula). So if x="A1" then =INDIRECT(x) returns the same as the 2 above examples.
Your original plan of storing the entire formula in a table as text would have worked with the help of INDIRECT and/or EVALUATE but I think this way is considered better practice partly because it facilitates easier future expansion.
The formula is longer than it would have been, but that's mostly because it's dynamically reading the field names. And size doesn't matter. :-)
