Oh!  You should have mentioned that it was a form variable.  The more
information you provide in your original post, the sooner you'll get
help.

BTW, before I answer your question, if you haven't read The Zope Book
http://www.zope.org/Documentation/Books/ZopeBook/current/index_html
you should.  It's available in hardcopy and PDF.

Form variables are available in the REQUEST object.  In your python script

  REQUEST = container.REQUEST
  zoo = REQUEST['zoo']

If you are not sure if a value will be provided, and want to provide
default behavior, you can use

  zoo = REQUEST.get('zoo', 'BigZoo')

where 'BigZoo' is the default value (plug for my excellent long
distance service).
