Well that makes total sense, and I didn't have it defined properly.  Its
still not working but I'm going
to continue withit for awhile.  Want thing I do seem to be gifted with
is persistence.

This is giving me the total only of the last item entered.  In another
version I'm at least getting a total for each item entered.  

You know I can visualize this so well but I just don't know how to say: 
Look at each item see what values it has and add up all those values in
to one number..in Python.
