Thanks for the suggestion, but I really am a novice when it comes to all 
this and you are probably presuming more expertise than I have.

I created a Page Template exactly as you suggested. It's called test and 
is in the testsite folder - the contents are pasted from your example. 

The python script was pasted into a file object called linkList  which has 
a Content Type of text/x-unknown-content-type.

When I load the 'test' file and click on the Test tab I get:-

Zope Error

Zope has encountered an error while publishing this resource.

Error Type: AttributeError
Error Value: __getitem__ 

Any ideas on what I have missed out or where to look for a working 
example?
