[Zope] simple question

[D. Rick Anderson]

This should be easy, but I can't seem to make it work. With this statement:

<dtml-var "webClient('http://192.168.107.8/SQL_Testing/Database_Test?
clt_id=&dtml-clt_id;')">

I can't get the &dtml-clt_id variable to render. I've tried all sorts of 
variations from leaving out the ; to using the full <dtml-var> syntax and 
it still wont render. When I look at the request that is sent it looks like 
this:

QUERY_STRING 'clt_id=&dtml-clt_id;' 

Why won't this work?!?! It seems like something REALLY simple, but I just 
can't get that thing to render right. 

Thanks,

Rick
