Hi,
I have a formula :
=SUMPRODUCT((('Totals'!$A$5:$A$11=J5:J11)*('Totals'!$B$5:$M$11)))
but it only returns the values for J5 J8 and J9, not 6, 7, 10 or 11, as
you would expect it to do. I have checked and the values it is looking
up are accurate (they work individually). Is this a problem with
sumproduct or am I just being a bit dim?

Thanks

Hi Sanders,

The SUMPRODUCT function needs arrays of the same numbers of elements, but
you ar multiplying an array of 7 (7 rows * 1 column) elements
('Totals'!$A$5:$A$11=J5:J11) by an array of 84 (7 rows * 12 column) elements
('Totals'!$B$5:$M$11), so it's right that the result is not what you
think... You have to fix the two arrray to have the same number of
elements... Check the on line help.

Hope I helped you.

Thanks in advance for your feedback.

Thanks for the quick response. I tested out what you suggested and
modified the formula to read:
=SUMPRODUCT((('Totals'!$A$5:$A$11=J5:J11)*('Totals'!$B$5:$B$11)))
So it is only looking at one column of 7 at a time. But it is still
only adding together the corresponding values in the B column for J5,
9, 10 and 11. Any ideas why this would be happening?

Thanks again
 
=SUMPRODUCT((ISNUMBER(MATCH(J5:J11,Totals!$A$5:$A$11,0)))*(Totals!$B$5:$M$11
))
