[Zope] external method import error (ImportError)...

[Eric]

Hi,

To summarize: How do I import modules in an External Method's .py file?

I have an external method that points to a .py file that has an import
statement at the top.  The import statement loads another module of mine
(CProject.py).  I've placed both files (pwToxml.py and CProject.py) in the
Zope/Extensions directory.  When I try to create an external method on the
pTox.py file with the following parameters:
ID = pTox
Function Name = pTox
Python Module File = pwToxml
I get the following error:
Error Type: ImportError
Error Value: No module named CProject
Traceback (innermost last):

ImportError: (see above)

I checked the sys.path for my Python installation and placed the CProject.py
file there, but I still get the same error.

Here's the top of my pwToxml.py file:

import CProject, string

def pTox(self, REQUEST):
    """Function to map pw to CProject Objects"""
    P=CProject.CProject()
    dictData = REQUEST.form.items()
    strTemp = ""
    strError = "Error Retrieving Dictionary Value"
    ...etc...

Thanks for any help you can provide.
