Question
QUESTION: Hi Tom
I would like to average a range according to the following criteria
BA7 is 7
A1:A1500 is 7
And
The number of cells in column N1:N1500 that are not empty.  However all of the cells in range N1:N1500 contain formulas.  I only want to average the cells for which the formula produces a number or text string.

Could explain how I might achieve this, please?

This is my unsuccessful formula:
=IF(BA$7=7,AVERAGEIFS($T$1:$T$1500,$A$1:$A$1500,7,N1:N1500,<>"")


Thanks in advance

Chris

ANSWER: Christopher Mitchell

I would try this

=IF(BA$7=7,SUMPRODUCT(--($T$1:$T$1500),--($A$1:$A$1500=7),--(LEN(TRIM(N1:N1500))>0)))

QUESTION: Hi Tom

The formula seems to produce a "value" error.  If I send a very small workbook to you, could you test the formula for me?

Thanks in advance

Chris

Answer
Christopher Mitchell,

that would occur if T1:T1500 had cells that were to be averaged that were not numbers.  

In any event, I was rushing to get to a meeting and only gave you the numerator.  The whole formula would be (adjusted to only accept numeric entries in T


=IF(BA$7=7,SUMPRODUCT(IFERROR(--$T$1:$T$1500,0),--($A$1:$A$1500=7),--(LEN(TRIM(N1:N1500))>0))/SUMPRODUCT(--($A$1:$A$1500=7),--(LEN(TRIM(N1:N1500))>0)))

but now it must be entered with Ctrl+Shift+Enter

If you want to send me a file, you can but I won't be able to see it for 6 or 7 more hours.
