Hi guys and sorry for my bad english.

I try to explain in a simple way my problem. For example: I want cell C1 to be equal to cell A100 (for example), but I don't want to write "=A100" in cell C1 because I want to obtain 100 as function (to give a simple example 50+50).

The problem is that I can't write in cell C1 "=A(somma((50+50))" because Excel will return an error.
How can I do thi apparently simple task?

Thanks
