Well it is submitting the POST VARS but you are redirecting it to another page so the POT Values dont get redirected.Hence it is not working.Instead of redirecting include the processing file in the same page if the $_POST['Submit'] is set or show the form.I doubt that this is even working in Internet Explorer or FireFox as this is not a brower issue but a PHP issue.Hope this works out.
