[Zope] Traversal issue...

[Rob Foster]

Ok, here's the setup...

I've got two adjacent folders:
Folder A - This folder has a form that will allow users to edit the 
properties of a specific zclass instance that resides in Folder B.
Folder B - This folder has a bunch of instances (each instance's id maps 
to the username of a user in the system)

Now, the users each have a cookie with their username set...

When they fill out the form in folder A, I want to update the instance 
in B that maps to them (based on the value of their cookie), but I can't 
seem to "get to" (traverse?) the right instance with either DTML or 
Python.

Any help would be appreciated as always.

Thanks,
Rob
