[Zope] Help!!!

[William P Hewitt]

For four days now, I have been trying to build some simple products -
using the Zope Book instructions on product creation and the basic
objects that are created when you follow the instructions.....
But to no avail - I always get this same error that I haven't a clue as
to what it means.....

Any help out there on what I'm doing wrong?
