Hi Eric
I tried your formula, but I can't seem to get it return the correct result.
When excel evaluate a statement, it return True or False, which will be
turnd to values (1/0) when you multiply theese results (or multiply by 1)
The 1 in the Match function is the value to match, but the function does not
return 1 or 0 but true or false, so if you replace 1 by true, you will not
get #N/A, but the value 700 which is the first match for the date.
I tried the sumproduct formula I have posted earlier, and changed the ranges
to the correct ones, and it returns the correct result on your sample data:
=SUMPRODUCT(--(X8:X900=B8),--(Z8:Z900=D8),--(AD8:AD900=J8),AF8:AF900)
Best regards,
