Zope error messages are better than the quotations I often see
in the mailing list. It tells you which name is not found!
As you surely understand this is an essential information.

  From your code above, I would expect "folder" is unknown.
  But that's probably because your just forgot to show
  us the definition of "folder"...

  The traceback suggests, "id" is unknown in "REQUEST".
  I expect that this is due to the fact, that
  "UserFileFolder_add" is a DTML method that is
  called wrongly (without the necessary 2 positional parameters).
  If this analysis is correct, then you should read the
  section "Calling DTML objects" in

    <http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html>

For the future:

  When you report tracebacks, you should report "Error Type"
  and "Error Value", too.
