[Zope] Newbie-ish dtml-with vs dtml-in question

Hello everyone, Is there a way to use the dtml-in tag, and not iterate over the results? The problem I'm having is that I can call a ZSQL method, and pull a variable out of it using dtml-in, and I get a nice iteration over that variable. But in the case of one of my variables, I just want to pull it out, without iteration. I've tried to do it with both dmtl-call and dtml-with, but they don't do what I want, and I get a key error for that variable. Can any one offer any hints at what I should do? Thanks! Russell
