If I'm understanding correctly(quick look at it), then write a new py file and __import__ it if I'm remember correctly. Use a secondary file to rewrite the existing nature of the python code file, then import it, and utilize the remade secondary py file for your usage.. -- Best Regards, David Hutto CEO: http://www.hitwebdevelopment.com -- http://mail.python.org/mailman/listinfo/python-list
