To get this to work, I had to do
 tal:repeat="item 
python:container.module_info(module_code=options['modcode'])"

A side effect of which was that I could then do

<dtml-var "mod_info(modcode='bgm')">

happily.

Thing is, I can no longer use the mod_info?modcode=eng structure from the
browser window. The variable doesn't exist in the options namespace, only in
the form namespace.

I would have thought that the options/modcode structure that Richard
mentioned is more in line with the thinking behind TAL? (I could be way off
- like I said, I'm coming from DTML-land).

Cheers
Tone.
