[Zope] Target Help

Hi all: I using the following: <dtml-let target="'index_html'"> <dtml-call expr="RESPONSE.redirect(target)"> </dtml-let> But I would like to add variables to the url like this: <dtml-let target="'index_html?me=<dtml-var name>&you=<dtml-var you>'"> This doesn't seem to work the way I would like, is their another way to do this? Thanks, Todd
