[ZPT] How do I use form variable to pass as a parameter to a python script?

[Daniel Tang]

I found the problem with the returning of null values:

Getting at Zope Objects

The tradeoff is that path expressions don't allow you to specify those
details. For instance, if you have a form variable named "get", you must
write "python:request.form['get']", since "request/form/get" will evaluate
to the "get" method of the form dictionary.


Thanks again for your help!
