I dont know what to do here?

Hello, I have a form in an htm file that is sending info to a cgi script (formmail.pl) but the confirmation page I am using is php3. I want to pass the value of a text box in the form to the php3 page. Kinda like thanks you message $message has been sent. I don't know how to send to the cgi script and pass the variable to the confirmation page. Here is my code so far for the form action. <form method="POST" action="/cgi-bin/formmail.pl?http://www.domainname.co.nz/developing/faq/faq_ confirm.php3"> So I need the faq_confirm.php3 page to appear, plus have it send the variable $message that is one of the fields on the form. I thought you just added it like ?message But i already have a ? Please help? Chris
