FLASH & PHP contact form issues (AS 2.0)

Can anyone help me figure out how to add a second message box to the code below.

This is a Flash contact form that uses PHP to send an email. The form works fine, but I’ve been trying to figure out the code to add a SECOND message to my email.

Currently when I run and fill out the form, I get the email, subject and message, but I want to add a second message field, let’s call it message2.

Here is the Flash and PHP code:

//////------Flash AS 2.0------------////////

send_btn.onRelease = function() {
my_vars = new LoadVars();
my_vars.sender = email_box.text;
my_vars.subject = subject_box.text;
my_vars.message = message_box.text;

if (my_vars.sender != "" and my_vars.subject != "" and my_vars.message != "") {
	my_vars.sendAndLoad("mailer.php", my_vars, "POST");
} else {
my_vars.onLoad = function() {

email_box.onSetFocus = subject_box.onSetFocus = message_box.onSetFocus = function () {
if (error_clip._currentframe != 1) {

//////------PHP code------------////////


// read the variables form the string, (this is not needed with some servers).
$subject = $_REQUEST[“subject”];
$message = $_REQUEST[“message”];
$sender = $_REQUEST[“sender”];

// include sender IP in the message.
$full_message = $_SERVER[‘REMOTE_ADDR’] . "

" . $message;
$message= $full_message;

// remove the backslashes that normally appears when entering " or ’
$message = stripslashes($message);
$subject = stripslashes($subject);
$sender = stripslashes($sender);

// add a prefix in the subject line so that you know the email was sent by online form
$subject = “web visitor:”.’ '.$subject;

// send the email, make sure you replace [email protected] with your email address
if(isset($message) and isset($subject) and isset($sender)){
mail("[email protected]", $subject, $message, “From: $sender”);
