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())
This is a module level variable, not a class attribute, right?
...
manage_addCampusForm needs to call:
tableSubmitButtons =
HTMLFile('campus_dtml/tableSubmitButtons',globals())
Which is in the same directory as "manage_addCampusForm".
That don't matter.

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....
If I understand what you're trying you have at least two choices:

*first*
pass explicitly the rendered tableSubmitButtons to manage_addCampusForm:

_manage_addCampusForm = DTMLFile(...)
_tableSubmitButtons = DTMLFile(...)
def manage_addCampusForm(...) :
   return _manage_addCampusForm(...,
                                buttons=_tableSubmitButtons(...))

and in the CampusForm DTML:

<dtml-var buttons>

*second*
add an extra constructor, so manage_addCampusForm can locate 
tableSubmitButtons:

from YourModule import manage_addCampusForm
from YourModule import manage_addCampus
from YourModule import tableSubmitButtons

context.registerClass(...,
                       constructors=(manage_addCampusForm,
                                     manage_addForm,
                                     tableSubmitButtons),
                       ...)

Just curious, why you separate the form from the submit buttons?
