[Zope] help with pygantt

[Aruna Prabhakaran]

hi all,

I am working on an application wherein I need  to generate gantt charts
using pygantt tool . When I run the script from the python shell prompt,
it is working fine, but raises an error when i try to do it in Zope
(using Zope 2.7 and python 2.3.2)

I get the following traceback :
------------------------------------
Traceback (most recent call last):
