Show variable result at the place of expression

expression
variables

#1

1) Give a description of the problem
Just add variable (local) that countain expression like: ( var_A = var_B + var_C). The variable Var_A show the expression in the piston but I want it to show the result!

2) What is the expected behaviour?
see result like if B=2 & C =3 then (Var_A = 5)

3) What is happening/not happening?
see the expression Var_A = Var_B + Var_C
No ideas of the result as long as I evaluate myself or edit the expression to get the evaluation…

4) Post a Green Snapshot of the pistonimage
