Mail form with checkbox

Attached is one form fla in AS 2. There are some input fields and one check box. the name of the check box is “Terms and Conditions”
What I like to do is to check the check box as an acceptance of the "“Terms and Conditions” and then the user can fire the mail form. And at the same time the received mail will reflect that the user is checked the check box ( Say Checked = yes, Not Checked = no). I could not solve the same . how can I do this .

Below is the php code which I want to modify and use with my mail form.Can any one come and help me.



<?php
    if ($_POST)
    {
        $mailTo = "CyanBlue@FlashVacuum.com";
        $mailSubject = "[Contact] Website Contact from - (" . $_POST['name'] . ")";
        
        $Header = "MIME-Version: 1.0
";
        $Header .= "Content-type: text/html; charset=iso-8859-1
";
        $Header .= "From: " . $_POST['email'] . "
";
        
        $output = "<BR>";
        $output .= "From    : " . $_POST['name'] . "<BR><BR>";
        $output .= "Email   : " . $_POST['email'] . "<BR><BR>";
        $output .= "About   : " . $_POST['about'] . "<BR><BR>";
        $output .= "Message : " . $_POST['message'] . "<BR><BR>";
        $output .= "Heard From : " . $_POST['from'] . "<BR><BR>";
        
        $output = nl2br($output);
        
        if (mail($mailTo, $mailSubject, stripslashes($output), $Header))
        {
            echo("&result=1&");
        }
        else
        {
            echo("&result=2&");
        }
    }
    else
    {
        echo("This script runs only in Flash!!!");
    }
?>
