I want to verify that certain fields in a form have been entered. Here's a code snippet I've tried to use:

<dtml-let required="('first', 'last', 'email')"> <dtml-in required> <dtml-if expr="REQUEST.form[sequence-item]"> <dtml-var sequence-item> exists </dtml-if> </dtml-in> </dtml-let>

The way to get around python choking on this is to look up sequence-item in the namespace: <dtml-if expr="REQUEST.form[_['sequence-item']]"> Kevin
