Ok I have 2 excel columns
1st column A "Workstream", is a data list with three numbers as a dropdown. 1,2,3
2nd column B "ID", would like to auto-populate based on the selection made from the left adjacent cell + perform a lookup to get the MAX number in the current column and ADD by 1.
For Example:
Workstream
ID
1
W1-001
1
W1-002
1
W1-003
1
W1-004
2
W1-001
1
W1-005
2
W1-002
So when a user selects from the drop-down in column A then Column B auto-populates with something like this
="W"&A:1&"-"
However, in order to complete the value, it needs to do the following:
="W"&A:1&"-" Search for the Max Record in Column B that starts with 1 or whatever value was entered into Column A, then include the next number based on the MAX value selected in Column A
So in the above example, let's say I Enter "2" in column A, then the value that auto-populates in column B would be
| 2 | W2-003
or if I selected 1 from column A given where we left off then the value that would auto-populate in column B would be:
| 1 | W1-006
If I am understanding correctly and you want the format to be "W" followed by number of the workstream (as inferred from the text of your question) try:
="W"&A2&"-"&TEXT(COUNTIF(A$2:A2, B2), "000")
If instead you want the output exactly as shown in the picture you provided, it's even easier:
="W1-"&TEXT(COUNTIF(A$2:A2, B2), "000")
EDIT: You might consider pre-dragging the formula to all the rows that you think have the possibility of being impacted so that you don't have to drag the formula each time you add a row. In that case, try:
=IF(A2="","", "W"&A2&"-"&TEXT(COUNTIF(A$2:A2, B2), "000"))

I have simple problem, but I've not be able to get an answer from searching. I require a column to calculate the number of the nth occurrence of a value. It's best explained in this picture
I require a method to calculate column B.
I'd be very grateful for any help.
Are you looking to merely provide a count of the distinct entries of column A in column B? Or merely add a formula to come up with the table in your link?
If the latter, then the formula to write in cell B2 is:
=COUNTIF(A$2:A2,A2)
then copy/paste it down column B. Note - if your data is both a Date and Time, but the cell is formatted to only display a date, you may not get the results you want. You'd need to interject a new column with a "floor" calculation to round the date/time value to a date (Excel date times are decimal, with integer part dictating the date, and remaining 0.0 -> 1.0 dictating the time of day)
If you just want to derive a table of the counts of distinct entries in column A, then a pivot table will do this for you - simple add a pivot table to cover the data in column A, then select column A into the rows category, and then also drag it into the values category, ensuring the field is set to "Count of". You should then have a table with the distinct entries in your data set in one column, and the count of their occurrences in the other column.
You can use the COUNTIF worksheet function, with a relative address.
Eg. In cell B2, enter this formula:
=COUNTIF(A$2:A2,A2)
And then fill-down.
Use the following formula to generate the required series:
=COUNTIF($A$1:A1,A1) and strech(copy) it in all the cells
This will generate result like this:
A 1 COUNTIF($A$1:A1,A1)
A 2 COUNTIF($A$1:A2,A2)
C 1 COUNTIF($A$1:A3,A3)
C 2 COUNTIF($A$1:A4,A4)
B 1 COUNTIF($A$1:A5,A5)
B 2 COUNTIF($A$1:A6,A6)
A 3 COUNTIF($A$1:A7,A7)
C 3 COUNTIF($A$1:A8,A8)
D 1 COUNTIF($A$1:A9,A9)
D 2 COUNTIF($A$1:A10,A10)
D 3 COUNTIF($A$1:A11,A11)
D 4 COUNTIF($A$1:A12,A12)
There are 50 rows. The first column (A), each row has has a ID number. They are not sorted in any way and should not be either and there are no duplicated ID numbers. When the ID is 0 then consider 4 rows before that row, take the mean value of those values in clumn C between those 4 rows. If it helps It is always the last row that has value ID = 0.
What I have done so far is that I can find the ROW number of the ID = 0 using the following formula:
ROW(INDEX(A3:A53,MATCH(TRUE,INDEX(A3:A53=0,),0)))
Now I don't know how to navigate 4 rows upwards and take the corrosponding values in Column C.
If you use an extra column (say column Z), then paste this code into that column starting on row 4 (NB it won't work properly for the first 3 rows because there are not 4 above to check).
=IF($A4 =0, AVERAGE($C1:$C4), "Not Relevant")
so put that code in Z4, then press ctrl+E to flash fill it downwards.
Hopefully, on each line where the ID is 0, there will be an average of that line and the previous 3 in column Z on that row.
Use:
=AVERAGE(INDEX(A3:A53,MATCH(TRUE,INDEX(A3:A53=0,),0)-5):INDEX(A3:A53,MATCH(TRUE,INDEX(A3:A53=0,),0)-1))
I am currently using the following subtotal SUBTOTAL(9,b:b) to cat a total on my filtered data.
Column A contains a year of either 16,17,18 or 19.
I would like to only count the subtotal if column A contains 16 so
=if(a:a = 16, SUBTOTAL(9,b:b) or something simular
We can "fake" the SUBTOTAL() function. Say we have data like:
and we want to filter the data and only add values in column B that correspond to 16 in column A. In C2 enter:
=SUBTOTAL(3,$B2:$B2)
and copy downward. Then filter column B for positive only:
The cool thing about column C is that it is 1 if the row is visible and 0 if the row is hidden. Therefore:
=SUMPRODUCT((B2:B20)*(C2:C20))
will yield the same result as =subtotal(9,b:b) and:
=SUMPRODUCT((A2:A20=16)*(B2:B20)*(C2:C20))
will apply the column A restriction.

I have 2 columns looking like this:
Column 1 Column 2
1 x
x 2
2 2
x x
1 2
I want to do two things;
For each row match (row n column 1 = row n column 2) it should mark cell n in column 1 green if there is a match and red if it is not.
It should create a sum cell where each match is worth 1 point, in this case column 1 should result in 2 points.
Is this even possible with excel and if so, how is it done?
For the first part of your question:
It should mark cell n in column 1 green if there is a match and red if it is not
You can do this using Conditional Formatting.
Ex:
Assume column A and column B, with the values starting in row 2.
The following conditional formatting would highlight column A values in green if they match the corresponding value in column B in the same row, otherwise red.
Highlight the values in column A, then apply this conditional formatting.
For the second part of your question
It should create a sum cell where each match is worth 1 point, in this case column 1 should result in 2 points
The following array formula will tally all the matches and show you how many there are:
=SUM(IF(A2:A6=B2:B6,1,0))
Assuming again that we are in columns A & B with your sample data.
Remember to commit this formula using Ctrl+Shift+Enter.
Per comment from andy holaday, here is another formula that will work:
=SUMPRODUCT(N(A2:A6=B2:B6))
or
=SUMPRODUCT(--(A2:A6=B2:B6))
These are not CSE formulas so you would not need Ctrl+Shift+Enter to commit them.
