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...

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.
