[Zope] passing form variables to ext. method

Hello again, Since I've beeen unsuccessful getting INSERT statements to work with PoPyDA/Zope/PostgerSQL, I've decided to use a web-form and an external method to process the form variable=value pairs. The python script works fine when I hardcode the values and run it from the command line, but trying chokes trying to get the query string (REQUEST) when called from a dtml document's form. I've been banging on it far too long and haven't found any documentation which has helped clear up the problem, so if anyone could point me in the right direction or send a code snippet to the mailing list, I'll thank you greatly. Thanks, Matt matt@bitflip.com
