import error?

[Tom]

Hi Peter,

thanks a lot for your explanations. I'll try what you suggested, but 
that looks like a lot of work,so I am not sure when I find time for 
that! :-)
But I will defintely consider your concerns about my programming for my 
next piece of code right from the beginning. :-) I had no idea that 
"from xxx import *"can cause so many problems and is kind of bad style.

Thanks again for your time. I appreciate that a lot.

Regards, Tom
