dispersion problem Eigenmode solver

Hi,
I am trying to simulate dispersion (phase vs Freq) plot through following "piboo" steps link '"https://www.edaboard.com/thread123197.html". But, Eigenmode solver+ parameter sweep+sequence1 (ph 0-180 (10))+"Add watch" I could not found Frequency mode 1,2 ...why?

I am trying to resolve this problem since long days...but failure every-time. Please if possible could you help me...to work out ?
