I am in the process of creating a Python Product for Zope with the
following directory structure under my Products directory.
                -FGDC
                    __init__.py
                     <all other .py modules that make up the metatypes
of the product>
                    -dtml
                           <my dtml forms>
                          manage_propertiesForm.dtml
                    -scripts
                         processProperties.py


I try to execute the script, processProperties, from inside
manage_propertiesForm.dtml. Right now, I am using a simple
        <dtml-var "processProperties">
call. However, I get a NameError saying that processProperties is not
defined. Here is my traceback:

            Traceback (innermost last):

           Module ZPublisher.Publish, line 98, in publish
            Module ZPublisher.mapply, line 88, in mapply
            Module ZPublisher.Publish, line 39, in call_object
            Module Shared.DC.Scripts.Bindings, line 252, in __call__
            Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec

            Module App.special_dtml, line 174, in _exec
            Module DocumentTemplate.DT_Util, line 201, in eval
            __traceback_info__: processProperties
            Module <string>, line 0, in ?
            NameError: name 'processProperties' is not defined

A Very simplified version of my script is here:

## Script (Python) "processProperties"
##bind container=container
##bind context=context
##bind namespace=_
##bind script=script
##bind subpath=traverse_subpath
##parameters=
##title=Process changes properties for validation before commitment to
property sheet
##

return 'abcd'

I have searched the world over to determine how to 'register/call' my
filesystem script from my dtml method with NO LUCK. Can someone please
guide me in the right direction? Thanks in advance.
