In general it is better to popst long listings (over 100 lines say)
to a web site such as pastebin. That will ensure they are readable
and will not fill up peoples mailboxes unnecessarily.

However, even better is to reproduce your error in a small sample
program so we do not have to read all of your code!

I can't speak for all of them but the first one I looked at had an error,
very similar to that suggested by your error message.

In this code the method assigns a value to items, then reassigns items to a 
modified list.
If the list is not empty it reassigns items to the first element. It then 
creates a new variable.
passing a variable item which does bot exist in the method so shouldbe defined 
globally.
But your error message suggests it is not. I suspect the items[0] assignment 
should be
to item? Or maybe to self.item?
