[Samir Mishra]

Please ignore my previous email, just realized I'd already figured that part
out.

Thx.

Thanks. Defining the code in a DTML method works. 

Now, for the second part - how do I go about generating the tree with the
branches and leaves as links? I'm sure this has been done before...

Samir.

Almost surely, this code is in a DTML Document (rather than DTML Method).

  For some unknown (stupid) reason the base class of most
  Zope object classes ("OFS.SimpleItem.SimpleItem") defines
  Object Manager methods (such as those used by "dtml-tree").
  Of course, these methods cannot return useful results.

  DTML Document looks first in its local namespace (and finds
  the bad Object Manager methods); only then it looks in
  the namespace defined by its context.

  DTML Method looks only in the namespace defined by its context.

As a general rule: do not use DTML Document -- unless you know
precisely what you are doing.
