and what's AddReRun()?

If you produce a minimal script to reproduce your problem without all the complexities of your current script (see Short, Self-Contained, Correct Example) AND indicating which variables are global (actually avoiding any will be easier), someone may be able to help you more than my general advice. As it is, I will not write a Tk script from scratch just to be able to help you - others may.
