Hi,
I'd like to sum the number in the right of the cell according to the left starting.
here the sample
That is to have in AH2 a sum of the numbers after "Fe" for example. In this case I'd have 16 in AH2 and 16 also in AI2 (the sum of all the "CI").
The sum must occour in the range B2:AF2.

Is it possible to sum in this way?
