[Zope] NameError when rendering a zsql-method in a dtml-method in a dtml-method

[Andreas Hölzl]

maybe this is a simple problem, but not to me as a beginner...

when rendering a dtml-method which renders itself a dtml-method which
calls zsql-method i get the following:

ErrorError Type: NameError
Error Value: There is no variable named 'name_of_zsql_method'

simple namespace problem?
playing around with "dtml-with" did not help.

please help me.
thanks in advance.
