Contact form problem

I have a very simple php and as3 contact form that is NOT working at all. the swf file works, but it never sends the email message to me.

here is my php code

edit: the email looks messed up with the php code tags around it

$receiver = ”j_murray0384@yahoo.com";
is the way it should read below


<?php
$contact_name = $_POST['name'];
$contact_email = $_POST['email'];
$contact_subject = $_POST['subject'];
$contact_message = $_POST['message'];

if( $contact_name == true )
{
    $sender = $contact_email;
    $receiver = &#8221;j_murray0384@yahoo.com&#8221;;(my email address is here)
    $client_ip = $_SERVER['REMOTE_ADDR'];
    $email_body = "Name: $contact_name 
Email: $sender 

Subject: $contact_subject 

Message: 

$contact_message 

IP: $client_ip;        
    $extra = "From: $sender
" . "Reply-To: $sender 
" . "X-Mailer: PHP/" . phpversion();

    if( mail( $receiver, "Flash Contact Form - $contact_subject", $email_body, $extra ) ) 
    {
        echo "success=yes";
    }
    else
    {
        echo "success=no";
    }
}
?>


and

this is my as3


contact_name.text = contact_email.text = contact_subject.text = 
contact_message.text = message_status.text = "";

send_button.addEventListener(MouseEvent.CLICK, submit);
reset_button.addEventListener(MouseEvent.CLICK, reset);

var timer:Timer;
var var_load:URLLoader = new URLLoader;
var URL_request:URLRequest = new URLRequest( "send_email.php" );
URL_request.method = URLRequestMethod.POST;

function submit(e:MouseEvent):void
{
    if( contact_name.text == "" || contact_email.text == "" ||
        contact_subject.text == "" || contact_message.text == "" )
    {
        message_status.text = "Please fill up all text fields.";
    }
    else if( !validate_email(contact_email.text) )
    {
        message_status.text = "Please enter the valid email address.";
    }
    else
    {
        message_status.text = "sending...";
        
        var email_data:String = "name=" + contact_name.text
                       + "&email=" + contact_email.text
                       + "&subject=" + contact_subject.text
                       + "&message=" + contact_message.text;
                       
        var URL_vars:URLVariables = new URLVariables(email_data);
        URL_vars.dataFormat = URLLoaderDataFormat.TEXT;
        
        URL_request.data = URL_vars;
        var_load.load( URL_request );
        var_load.addEventListener(Event.COMPLETE, receive_response );
    }
}

function reset(e:MouseEvent):void
{
    contact_name.text = contact_email.text = contact_subject.text = 
    contact_message.text = message_status.text = "";
}

function validate_email(s:String):Boolean 
{
    var p:RegExp = /(\w|[_.\-])+@((\w|-)+\.)+\w{2,4}+/;
    var r:Object = p.exec(s);
    if( r == null ) 
    {
        return false;
    }
    return true;
}

function receive_response(e:Event):void
{
    var loader:URLLoader = URLLoader(e.target);
    var email_status = new URLVariables(loader.data).success;
    
    if( email_status == "yes" )
    {
        message_status.text = "Success! Your message was sent.";
        timer = new Timer(500);
        timer.addEventListener(TimerEvent.TIMER, on_timer);
        timer.start();
    }
    else
    {
        message_status.text = "Failed! Your message cannot sent.";
    }
}

function on_timer(te:TimerEvent):void 
{
    if( timer.currentCount >= 10 )
    {
        contact_name.text = contact_email.text = contact_subject.text = 
        contact_message.text = message_status.text = "";
        timer.removeEventListener(TimerEvent.TIMER, on_timer);
    }
