Try:

=SUMPRODUCT((B2:B40="DSO")+(B2:B40="OOJ"),(C2:C40) )

Good morning:

I'm running XL 2007, SP1 under WinXP.

I need to sum a range based on whether another range is either "DSO" or
"OOJ", i.e =SUMIF(OR(B$2:B$40="DSO","OOJ",),C$2:C$40)This formula obviously
doesn't work, and I can't seem to get the syntax correct. Should I be using
the double hyphen here?

Thank you for your assistance.
