Vorpal, I'm not sure how to answer your direct question,
but if you read the wsc documentation, then you will find
a different way of passing back event parameters, i.e.,
by using the oEvent "Event Object" created via the
"CreateEventObject" method.
Look up the "fireEvent Method" in the "microsoft windows
script component" documentation. You can (probably) find
the documentation somewhere on the microsoft scripting
website, but I have attached a copy of that page (in html
-- hope it can be read o.k., and if not I'll just send
it in text).
cheers, jw

<p>The following partial script component is derived from a calculator script component sample. Whenever
the result changes, the script component fires a custom onResultChange event back to the page,
passing the result as an expando property of the event object.</p>

script in the <script> element opaque. For details, see <a href="letXML.htm">Script Component
