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)
