Contact Form to Email

Hey everybody,

Have been stuffing around trying to get this tutorial working,
Everything seems to be working properly however, no emails appear in my inbox,
I think the problem lies in the URL to the php, or perhaps it’s sitting on my server incorrectly…
here’s the code:

submit_btn.addEventListener(MouseEvent.CLICK, sendMessage);
function sendMessage(e:MouseEvent):void
{
    var my_vars:URLVariables = new URLVariables();
    my_vars.senderName = name_txt.text;
    my_vars.senderEmail = email_txt.text;
    my_vars.senderMsg = message_txt.text;
    
    var my_url:URLRequest = new URLRequest("mail.php");
    my_url.method = URLRequestMethod.POST;
    my_url.data = my_vars;
    
    var my_loader:URLLoader = new URLLoader();
    my_loader.dataFormat = URLLoaderDataFormat.VARIABLES;
    my_loader.load(my_url);
    
    name_txt.text = "";
    email_txt.text = "";
    message_txt.text = "Message Sent";
}

//

<?php
$to = "[email protected]";
$subject = ($_POST['senderName']);
$message = ($_POST['senderMsg']);
$message .= "

---------------------------
";
$message .= "E-mail Sent From: " . $_POST['senderName'] . " <" . $_POST['senderEmail'] . ">
";
$headers = "From: " . $_POST['senderName'] . " <" . $_POST['senderEmail'] . ">
";
if(@mail($to, $subject, $message, $headers))
{
echo "answer=ok";
}
else
{
echo "answer=error";
}
?>

Any help or advice is greatly appreciated
Thanks
