Calculating more than 2 fields?

[Victor Congionti]

I have to add more than 2 fields together in a transaction to get the final amount however it appears that i'm only allowed to add 2. See screenshot. Thanks for your help in advance.

You'll have to just chain several such rules together.  For example, to total S1, S2, S3 and S4, you might do something like:

SubTotal = S1 + S2
SubTotal = SubTotal + S3
SubTotal = SubTotal + S4

This simplified approach gets rid of any issues related to order of precedence for operators or the use of parentheses in typical programming.
