Hi Mike,

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.

Trevor,

With your 'numbers in a1 - d1 try this

=SUMPRODUCT((LEFT(A11,1)="S")*(RIGHT(A11,LEN(A 11)-1)))

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)
