I am taking the sumproduct of three columns using the following formula
=SUMPRODUCT(--($M11=Data!$F$2:$F$100),--(Data!$DT$2:$DT$100=N$9),(Data!$I$2:$I$100))
The problem is that if I have any N/A's in either of these three columns (F,DT and I) I get an N/A returned, even if I should be having a value returned.
thanks
Paul
