[Zope] Passing parameters to python script objects

[Peter Sabaini]

Hi,

inside an expr you cannot use DTML anymore. Everything inside "" is a
kind of Python parallel universe ;)

So, you'd just use something like (untested):

<dtml-in ...>
  <dtml-var expr="myFunction(myField1)">
....

ru,
peter.
