You don't need to use OR.

=SUMPRODUCT(--(MONTH('Raw Data 2008'!A2:A1528)=1),--('Raw Data
2008'!B2:B1528<"XIAPPLXRP110"),--('Raw Data 2008'!B2:B1528<"New Website"))

Good Morning,

I have an expression =SUMPRODUCT((MONTH('Raw Data 2008'!A2:A1528)=1)*('Raw
Data 2008'!B2:B1528<"XIAPPLXRP110")) in which I would like to add another
criteria.

I would like to say not "XIAPPLXRP110" or "New Website"

I have never learned the way to say "or" in a formula.

Thanks, AP
