Email recieved but blank

I recieve the email just fine but the regardless of what I type the text is blank.

?

<?PHP

$to = "info@mywebsite.com";
$subject = "Contact from webSite";
$message = "Name: " . $theName;
$message .= "
Email: " . $theEmail;
$message .= "

Message: " . $theMessage;
$headers = "From: $theEmail";
$headers .= "
Reply-To: $theEmail";

$sentOk = mail($to,$subject,$message,$headers);

echo "sentOk=" . $sentOk;

?>
stop();

var senderLoad:LoadVars = new LoadVars();
var receiveLoad:LoadVars = new LoadVars();

sender.onRelease = function() {
    senderLoad.theName = theName.text;
    senderLoad.theEmail = theEmail.text;
    senderLoad.theMessage = theMessage.text;
    senderLoad.sendAndLoad("http://eliocamacho.com/newSite/php/send.php",receiveLoad);
}

One other question could I get the IP address of the sender?
