I created a very simple html page containing only the form information,
and a function called Test() which contained the javascript alerting the
value of custHidden. The test function was executed upon clicking a link
in the HTML. This behaved as one would expect, displaying [object] in
the alert. Are you executing the javascript *after* the page has loaded?
If the javascript is inline, then the field will not necessarily exist
at runtime.
