[Zope] Newbie: Help with dtml-tree

I have been trying to get a very simple tree up in ZOPE but nothing comes up. Now I am trying just the most simple example I can find, still nothing. What is the most basic tree code just to see it work once? Should this work "AS IS": <dtml-var standard_html_header> <dtml-tree> <dtml-var id> </dtml-tree> <dtml-var standard_html_footer> __________________________________________________ Do You Yahoo!?
