Like I have said before, if I "manually" navigated to the
RedirectHellpForm page , then reload the first page (RedirectForm),
and press the Submit button from the RedirectForm, it can find the
"name" of RedirectHelpForm.
My questions is how can I setAttribute("RedirectHelpForm" ...) before
navigated to the RedirectHelpForm page??
thanks
Sam
