make sumproduct lookup case sensitive

P

PBcorn

I'm using sumproduct to look up a value in column 5 based on values in
columns 1 and 2:

SUMPRODUCT((TRIM('Sheet1'!$A$9:$A$97)=TRIM(A13))*(TRIM('Sheet1'!$B$9:$B$97)=TRIM(B13)),'Sheet1'!$H$9:$H$97)

however i need it to treat two strings, identical aprt from the case of
certain letters, as separate items.

Any suggestions?
