=SUMPRODUCT((LEFT(A11)="S")*VALUE((MID(A11,2,2 0))))
VALUE is needed if there are any empty cells

Hi Bernard,

I just came across one problem with the formula that I haven't been able
to
figure out. It doesn't seem to work, if 1 of the cells in the array is
blank... is there a way of putting in a condition where it ignores the
blank
cells?

Thanks again.

Is it possible to use the Sumif function to add numbers with a specific
designator in front of it?

Eg.
A row contains strings like: S8, S10, V5, S5

Is there a formula that can total the S's? (Total would be 23)
