You can't use OR, you can use addition to simulate it - just like you are
doing with AND for multiplication.

=SUMPRODUCT(((B3:B33="")+(B3:B33="R")),--(C3:C331))

thanks for the clarification. just out of curiosity, is it possible to
use
or with sumproduct? something like
=SUMPRODUCT(OR((B3:B33=""),(B3:B33="R"))*(C3:C331 ))

=SUMPRODUCT((B3:B33="")*(C3:C331))

Hi Gary,

Try:

=SUMPRODUCT(ISBLANK($B$3:$B$33)*($C$3:$C$331))
