[Zope] Multiple values

Hi, I'm trying to update multiple values in one form at one time. In the first form i've put something like this: <dtml-in sqlquery> <input type=text name=ab:list value=<dtml-var x>> <inpu type=text name=cd:list value=<dtml-var y>> </dtml-in> and I've sent the lists to another page that contains something like this: <dtml-in "map(None,ab,cd)"> <dtml-call "sqlUpdate(i=sequence_item[0],j=sequence_item[1])"> </dtml-in> but its not working....
