Thank you everybody !

If Tkinter hadn't been so polite... but without any error message I 
didn't know where to start to search. It is a shame that one can't pass 
parameters through 'command' in a simple manner. My intent was to make a 
function that could be of use in as many cases as possible. I was 
experimenting way off the intented target of the exercise. Nevertheless 
it was an occasion to learn a whole lot.

Thanks to Simon and Eric the adresses too.
