Use <dtml-var "REQUEST.set('name', '[]')"--> and <dtml-var
"_['name'][index] = value"-->.  There is explict support for lists in
forms but cannot recall it currently.

On your form, set the target in your action button to point to the same
page and unpack the new list from REQUEST.forms and rebuild the page.
Esstentially, the user adds stuff to a form, the "Submit" reloads the same
page with the new data via a query string.  Zope then uses the new data
(prehapes with if statements) to rebuild the page.
