[Zope] get fssession value

Hello, I'm sure this is simple, but have not been able to come up with the correct way. If I do this, <dtml-call "FSSession['username'].update(REQUEST.form)"> and then retrieve with, FSSession['username'] I get {'username':'something'} when of course all I want is something. Thanks much, Rick --== Sent via Deja.com http://www.deja.com/ ==-- Before you buy.
