[Zope] Problem: Calling DTML Method from ZPT

Hi! I am having problems executing a DTML Method from a ZPT. I have been unable to find documentation regarding whether this is even possible or not. Here are a couple of examples: <!-- With this snippet, I get the DTML unrendered: --> <p tal:replace="python:root.games.hangman.index_html"></p> <!-- With this snippet, I get a TALES error and a big stack trace: --> <p tal:replace="root/games/hangman/index_html"></p> Anybody have any ideas what it is that I am doing wrong? I like ZPT conceptually, and ran into this snag while converting some of my DTML. (I am running Zope 2.4.0 with the latest hotfix.) Mike
