Values and variables for Tk radio buttons

[richard_chamberlain]

Hi Mark,

Briefly (I'm just on my way out of the door) you should use IntVar instead.

To get the contents of StringVar or IntVar by the way would be
IntVar.get() - so in your case that would be servar.get() (or for that
matter servar.set(A number) )
