[Zope] (no subject)

I am new to using Zope, but have been succesfull at using a psql input wizard to generate forms to dump data to a postgresql table. However, I have a dilema. I would like to generate a form that can dump multiple inserts to a variable, say x1 into a table. However, there is an additional variable, x2 that would have to be only entered once and would be the same for every record for which a different x1 is entered. I would like the user to enter up to 50 records for x1. Looking at dtml syntax it seems the <dtml-in> should do this. Could anyone point me to any examples or provide some help?
