The part (LEFT(A11)="S") will return Boolean FALSE/TRUE
But when Excel does math (here multiplication) on Boolean it converts this
to 0/1
Similarly text that can be converted to numbers will get cohered to numbers
with in a math operation.
So VALUE is not needed

Thanks Bernard, This formula worked perfectly for me as well.

The same with the note I left on Mike's formula, I also had to use the
"value(..)" formula in order to have it it take the last part of the
number
as a "number" value.

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)
