[Zope] calling a DTML Method from a DTML MEthod from a Python PRoduct...

Ive got a need to call a DTML Method from a DTML Method I call in a Python Product: In the Python File, I use to call the Creation Form (a DTML Method): manage_addCampusForm = HTMLFile('campus_dtml/CampusAddForm',globals()) manage_addCampusForm needs to call: tableSubmitButtons = HTMLFile('campus_dtml/tableSubmitButtons',globals()) Which is in the same directory as "manage_addCampusForm". Where do I put the second method above so that the Python Product/first DTML method finds it? so far I have tried to just add it to the bottom of the file and in the Class Definition - but I get an error that the "tableSubmitButtons" method cant be found.... What am I doing wrong here? TIA WPH
