Adding new field to form and PHP

Hi,

I am using this script for my first simple mailform:

<?php
$sendTo = “blabla@winder.demon.nl”;
$subject = “Videoproducties”;

$headers = “From: " . $_POST[“name”] .” <" . $_POST[“email”] .">
";
$headers .= "Reply-To: " . $_POST[“email”] . "
";
$headers .= "Return-path: " . $_POST[“email”];
$message = $_POST[“message”];
mail($sendTo, $subject, $message, $headers);
?>

I have added an extra input text field to my flash form, and gave it the var name ‘question’ . How should i add this in the PHP script??

Another question is:
Can I add a checkbox to a form like this?
How should I add that to the PHP script (I can’t give a var name to the checkbox in Flash, can I?)

Thank you very much!
