Thread: Problem with IF statement within a COUNTIF statement

Hello,

I am trying to have a cell in sheet "Summary" count the number of cells in column DX of sheet "Analyses" that are greater than 0, provided that the value in column A of "Analyses" corresponds with the value in B8 of sheet "Summary."

(In "Analyses," there are 106 subjects, each taking up 64 rows. So, columns 1-64 correspond to Subject 1, columns 65-128 correspond to subject 2, etc. In column DX, each subject has 64 values that are either 0 or greater than 0. In "Summary," each subject has one row that summarizes the 64 trials. I want a single cell in the "Summary," sheet to reflect the number of times each subject produces a value greater than 0 in column DX of "Analyses.")

I tried using this formula, but it did not work correctly:

=COUNTIF(IF(Analyses!$A$1:$A$10000=Summary!B8,Analyses!$DX$1:$DX$10000,""),">0")

(Summary!B8 = 1, so I am trying to calculate the number of values in DX that are greater than 0 only for subject 1.)

When I press enter, this yields a value of 384. This is impossible, given that subject 1 only has 64 possibilities of yielding a value greater than 0. Subject 1 has 2 values in column DX that are greater than 0.

I tried making this an array formula by pressing Shift+Ctrl+Enter, and that just gives me a #VALUE! error.

What am I doing wrong?

Thanks in advance!

Hello

Try;

=SUMPRODUCT(--(Analyses!$DX$1:$DX$10000>0),--(Analyses!$A$1:$A$10000=B8))

Perhaps

=SUMPRODUCT(--(Analyses!$A$1:$A$10000=B8),--(Analyses!$DX$1:$DX$10000>0))
