i highly recommend buying a python book....i liked the "Python Essential Reference" by David M.

(if not, something else - it's not an intro-to-oop book) http://www.amazon.com/Python-Essential-Reference-Developers-Library/dp/0672328623/ref=sr_1_1/105-2347441-5534819?ie=UTF8&s=books&qid=1184942097&sr=8-1 Greg wrote: > Ok...on to a new problem.
