The code is situated towards the end of a web page with the usual tags
-
<HTML>
<HEAD>
title, and other paraphernalia
includes for style sheets
</HEAD>
<BODY>
include files for menus for the page
html to capture form information
and php processing to do the jump
</HTM>
are you saying the code to do the jump must be the very first thing in
file and that's it?
