[Zope] Zclass methods and intermethod communication

Lets say I start a new product and add Zclass, by the book. Firstly on the methods view, I add a python script that counts from 1 to 10, called count. Secondly I add a dtml-method that calls <dtml-in "count()"> ..... </dtml-in> Oops count object not found ? ! How do methods talk to eachother ?? I must be missing something Chris
