Global evaluation

Hi,

I am trying to evaluate a surface average of potential (voltage) over a surface.

I do Definitions - model couplings - average and then list the surfaces over which I need to calculate the average.

Then under Definitions - Variables, I define Volt = aveop1(V)

Then under Results - Derived Values - Global evaluation I type Volt and click evaluate and I get the following error message.

- Variable: Volt
- Global scope:
Failed to evaluate expression.
- Expression: real(Volt)
Failed to evaluate expression.
- Expression: real(Volt)

Can someone explain why this is not working. I even tried mod1.Volt and its still giving me error
