[Zope] REQUEST

I'm trying to insert the REQUEST object into a new DTML document to record errors on a page. It doesn't seem to like the way I'm doing it and I can't figure out how to get it to work. I tried: <dtml-call "REQUEST.set('newname', ZopeTime().strftime('%m-%d-%Y-%H-%M'))"> <dtml-call "manage_addDTMLDocument(newname, 'Error', 'REQUEST')"> and I get a Key Error: Error Type: KeyError Error Value: read I've tried creating the document first, and then using manage_edit to insert it, and the same thing happens. I really need to dump the REQUEST object somewhere when there's been an error so I can see what happened. TIA Rick
