Okay, after leaving my problem alone for a couple of hours, and getting 
back to it this evening, i solved my problem within 10 seconds by making 
those text entry widgets global (see updated code at URL above).

As I am trying to write clean and profound code, i just would like to 
ask if this is a quite often used technique for solving this kind of 
problems (i have always been taught that global vars are *bad*).  If 
not, then what is the 'clean' technique to solve my problem?

Greetzzz,
Bart
