how to combine these two exp and give them singlr name

[#1]

exp1=       if([Customer Number Act]='789QWA','DIR',

exp 2 =    if([Customer Number]='9977YU','COMM', null()))

now i need to add these two exp and name it as total

and this total should show me the values of exp1+exp2

for example exp1=23  and exp2= 46

this one i will be using in the script

then total = 69

Can you provide some more detail on what you want with some sample data?

[#3]

Can you try using doller sign expression?

eg =Sum(exp1+exp2)

[manideep78]

You can add both expressions directly

Expression_1 + Expression_2

You will get sum of those two Expressions.

Eg:  If([Customer Number Act]=................) + If([Customer Number]=..................)

                           23               +               46

So the result will be 69.
