Module calling-newbie question

[Roland Hedberg]

Hi!

I'm having problems with using modules. I'lls start with the error as it 
is presented:

Exception in Tree control callback
Traceback (most recent call last):
   File "/local/develop/apacheadmin/Tree.py", line 427, in PVT_set_state
     self.widget.get_contents_callback(self)
   File "sexptree.py", line 11, in getelements
     for element in spo.sublist(node):
   File "/local/develop/apacheadmin/sexp.py", line 103, in sublist
     ss = string.split( subspec, "/" )
   File "/usr/local/lib/python2.3/string.py", line 121, in split
     return s.split(sep, maxsplit)

I using the tkinter based Tree.py module Charles E. "Gene" Cash and have 
built one module sexp.py which among other things tries to split a 
string. Really nothing fancy but it fails when the sexp module is used 
by a python program sexptree.py (also by me).

Sexp.py as well as sexptree.py imports string.

What more can I do ??
What am I doing wrong ??
