How to use HFSS macro to control field calculator?

I need to calculate the voltage drop along a line, but the field calculator cannot get the complex voltage through a range, so maybe a macro is helpful.

Can someone give me any suggestion?

Thanks

Calculator is OK. You only have to do it separately for Real (Cmplx->Real) and Imaginary (Cmplx->Imag) parts of a voltage.

Thank you very much, navuho.

Before your reply, I have found this solution, but I want to practice macro.
