Ok I have half of this equation working, and I'm hoping someone can help me
finish it off.

=SUMIF(W3:W10,"x",Q3:Q10) (***This works***)

if Q3 (for exmple) does not have an "x" i want to multiply W3 and H3 and add
that total to the above equation.

Column H = Pieces
Column W= Weight
Column Q= determines if Column W is gross or net weight.

This seems like it should be simple, I just can't tell what I'm missing.
