Count blank cells - excel

I'm having difficult for generate a formula to count the blank cells in a range of cells.
So here is the example, the output is expected in the second row and the counting area is in the first row.
I would like the to count the blank cells between the "AAA"s and every cells of output row has a value.
I have tried "countblank" and "counta", but apparently they don't work.
enter image description here

Try:
Formula in B2:
=MATCH("?*",C1:Q1,0)
Dragged right to P1.
For any input, including numbers:
=MATCH("?*",C1:Q1&"",0)

Count non blank cells above a cell until first blank

how do I count how many non blank cells until the first blank above a cell.
For example, it is 6 non blank cells from C15 to C6 until there is a blank cell C9. The array formula I know =Match(1,--(C5:C16=""),0)-1, always start counting from C5. Is there way to start backwards, like start counting from C16?
enter image description here
Instead of MATCH use MAX: `=MAX((C$5:C16="")*(ROW(C$5:C16))'.
Note, I used the Range you used in your example and locked the row at C$5 by using $-sign. That way it will not change if you drag down the formula.
This formula will return the ROW # of the condition met. If used in combination with INDEX I recommend referencing the whole column, like so:
`=INDEX(C:C,MAX((C$5:C16="")*(ROW(C$5:C16)))'
I noticed you substracted 1 of the row. You can do the same after this formula.

multiplying cells and sum then for a range

In my excel template, I need to have a formula to multiply two numbers with 2 or 3 conditions, and then sum the found numbers in an area.
For example;
First range is; AI22:AI1100
Second range is; AB22:AB1100
Third range is; N22:N1100
Fourt range is; K22:K1100
For first formula, i need to check the second range, found the cells that contain the same value as A2, then get the row number, find the value of the first range/that row cell, then divide it to its fourth range, and go on like this till AB1100 and sum all of that found numbers.
For second formula, i need to check the second range, found the cells that contain the same value as A2, then get the row number, check the third range if its the same value as A3, if it is then find the value of the first range/that row cell, then divide it to its fourth range, and go on like this till AB1100 and sum all of that found numbers.
I tried those with sumproduct, but it only sums both ranges and divides them in the end.
I can write this in Vba, but I need to store the values in the worksheets, so it will be better if I can do this in a formula.
I am open to suggestions.
You want SUM() as an Array formula
=SUM(IFERROR((AB22:AB1100 = A2)*(AI22:AI1100)/(K22:K1100),0))
And:
=SUM(IFERROR((AB22:AB1100 = A2)*(N22:N1100 = A3)*(AI22:AI1100)/(K22:K1100),0))
Being an array formula it needs to be confirmed with Ctrl-Shift-Enter instead of Enter when Exiting Edit mode.

How to refer to multiple adjacent cells

I have a work sheet in which there are several cells with a specific entry - let's say "A". These are not all in the same rows/columns. After each cell is a date.
I need to count the number of cells containing "A" which also have a specific date in the cell immediately to its right. I've tried combinations of Countifs and Indirect, with no success. How can I achieve this?
This counts the number of times that there is A in column A and 1 in column B
=SUMPRODUCT(($A$1:$A$5="A")*($B$1:$B$5=1))
This outputs in cell D1
Not too difficult.
I have created a sample sheet with 8 rows and 5 columns of data.
See below, the formula in cell C12 counts the number of occurrences where the a cell with a date of October 31, 2017 is directly to the right of a cell that contains the text A.
If you want more info as to how this works, read on:
When searching for cells that contain A, you don't search in the last column of the data (in this case, column E) because it is impossible for a column to the right to have any date in it. This is why a portion of the formula says A1:D8="A" instead of A1:E8="A". This is the same reasoning why we start searching for a date in column B rather than column A in the formula.
You can achieve this with a helper row. Add additional row on top of your Worksheet. In cell "A1" enter formula below.
=COUNTIFS(A2:A2000,"A",B2:B2000,"YourDate")
Drag this formula to the rightmost of where you have data, then simply sum all values returned by formula.

if cell blank leave cell blank if a number categorize

I need to come up with a formula that leaves cells blank when no value is entered and if value is entered it needs to categorize it in 3 levels, like in example:
I have use following formula but it reads blank cells as 0:
=IF(AND($AF4>=0,$AF4<=100),"1","0")
=IF (ISBLANK (AF4),"",IF(AND($AF4>=0,$AF4<=100),"1","0"))

Count number of blank cells in row between last cell and next non-blank cell

Is it possible (with a formula preferably) to count the number of blank cells in row, where the counting starts at a given column and counts going backward (e.g. right to left) the number of blank cells until a non-blank cell is found? In the example below, the counting begins at Column H and proceeds leftward. Using COUNTA or COUNTIF seem like reasonable tools to use, but I am unsure on how to terminate the counting once a non-blank cell is found.
You can use something like this if the values in your table are all text:
=COUNTBLANK(INDIRECT(CHAR(97+MATCH("zzzz",B2:H2))&ROW()&":H"&ROW()))
MATCH("zzzz",B2:H2) returns the column number in which the last non-blank cell is.
CHAR(97+ column number) returns the letter of that column.
Append it to the row number to give the reference where the COUNTBLANK has to start with &ROW()
&":H"&ROW()) gives the reference of the last cell, which is H plus the row number.
INDIRECT turns the concatenated text into a range that Excel can evaluate.
Try this formula
=COLUMNS(B2:H2)-MATCH("zzzz",B2:H2)
You could use nested if statements
=IF(ISBLANK(H2),IF(ISBLANK(G2),IF(ISBLANK(F2),IF(ISBLANK(E2),IF(ISBLANK(D2),IF(ISBLANK(C2),IF(ISBLANK(B2),IF(ISBLANK(A2),8,7),6),5),4),3),2),1),0)
