Where are your calling the DTML Method from?  Is the call in a
Script (Python) in the same folder as the DTML Method?

If so, here is an example:

    # Call the DTML Method "show_hippo".
    #
    request = context.REQUEST
    dtml_method = context.show_hippo
    # Call the dtml method.
    s1 = dtml_method(client=context, REQUEST=request)
    # s1 now holds the rendered html
    return s1

There is some explanation in "The Zope Book Chapter 15:
Advanced Zope Scripting"
(http://zopewiki.org/ZopeBookChapter15AdvancedZopeScripting);
search for the section titled "Calling DTML from Scripts".
