[Zope] Accessing folders

[Chris Pedrotti]

I'm new to all this, so please be patient.  What I am doing at the moment is
using <dtml-tree> to construct an html form of catagories for users to
submit images to.  I was setting the value of the radio buttons to
tree-item-url and then hoping that I could just replace all '/' to '.' to
access the folder that I wanted to image submitted to, and call
manage_addImage.

I was using <dtml-let> to assign a var to the folder url with the .'s and
then calling <dtml-call "_[submitfolder].manage_addImage(id='', file=file,
title='')">

Not working.  Could anyone please point me in the right direction?  Thanks.
