Hi, I'm trying to convert the value of two variables (fields) into one variable, something like this:

A + B = AB
AB -convert to- other

This new variable (AB) is the one that I want to convert in other. I shearched for examples or help but I din't found anything. In any case, Is that posible? and if is it, how?

Thanks :)
