Hi,
I am using a sumproduct as a SUMIF across two separate workbooks - Data is in one and the sumproduct is in a dashboard on the other. I need to sum one column - AE if a value from cell B1 exists in column C of the source data and then / it by the same sum of column AF to produce a % end result. my formula works fine but there are #N/A in the source data (which is a report I don't own) so I can't remove them. the formula I am using is:
=SUMPRODUCT((--('[DLS Error Report 2019 MASTER.xlsx]Error Summary By Branch'!$C$7:$C$851=$B$1)),('[DLS Error Report 2019 MASTER.xlsx]Error Summary By Branch'!$AE$7:$AE$851))/SUMPRODUCT((--('[DLS Error Report 2019 MASTER.xlsx]Error Summary By Branch'!$C$7:$C$851=$B$1)),('[DLS Error Report 2019 MASTER.xlsx]Error Summary By Branch'!$AF$7:$AF$851))
How can I get this to IGNORE the N/A values in column C? there are no N/A values in columns AF and AE.
Thanks
Jen
