Thanks very much for your quick responses!

This produces an AttributeError, with an ErrorValue: _hash_.

As this is given, it produces a Site Error because Zope is looking 
for the URL of the Python script. I get "can't find resource 
'/PythonScript%20instance....' on the error page.

Perhaps I need my Python script to be an external method? Right now, it isn't.

FWIW, the Python script (name=pagetoget), simplified so you can see 
what I'm trying to do more clearly, is simple:

daynum=1  #in the real script, this is a calculation but I've elimianted it
return 'http://www.mysite.com/fuzz'+daynum+'.html'

I'm pretty sure this returns a string that at least looks like a URL 
because if I just use:

<dtml-var pagetoget>

I get a page with the URL I expect to see 
(http://www.mysite.com/fuzz1.html) displayed.

Thanks. That's an easy rule to remember!

Ditto.
