SUMPRODUCT Difficulties

[Paxman71]

I am using this SUMPRODUCT formula =SUMPRODUCT(--($C$32:$C$1177=$C8),--($D$32:$D$1177=$D8),--($E$32:$E$1177))

and I'm getting the #VALUE! as a result.

Although when I copy a cut down version of the data into another file =SUMPRODUCT(--($C$22:$C$105=$C6),--($D22:$D105=$D6),--($E$22:$E$105))

this works perfectly. Could this be that the person I received the file from is using an older version of excel, and if that is the case what can I do?

Thanks.

Attach a sample workbook. Make sure there is just enough data to make it clear what is needed. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate. Make sure your desired results are demonstrated, mock them up manually if needed. Remember to desensitize the data.

Remove the double unary minus from the sum range:

=SUMPRODUCT(--($C$32:$C$1177=$C8),--($D$32:$D$1177=$D8),$E$32:$E$1177)

Or, better yet, use SUMIFS:

=SUMIFS($E$32:$E$1177,$C$32:$C$1177,$C8,$D$32:$D$1177,$D8)
