Anything you want passed to your ZSQL method must be defined as an
argument. They come from the REQUEST object, so they can be passed
directly from a URL defined variable.

BTW:

The dtml syntax you are using <!--#blah--> has been deprecated in favor
of <dtml-blah>. I'm not sure if DC is intending on supporting the
deprecated syntaxes forever, so it might be a good idea to use the
favored syntax.
