PHP and Flash Form help

[Animosity]

Well, I got this from a tutorial across the web and I saw a post from this website concerning with what I had. Though nothing works, I'm trying to see what can I do to have the content simply send in and flow though.
Flash:

stop();
System.useCodepage = true;
send_btn.onRelease = function() {
	my_vars = new LoadVars();
	my_vars.sender = email_box.text;
	my_vars.subject = subject_box.text;
	my_vars.name = name_box.text;
	my_vars.email = email_box.text;
	my_vars.company = company_box.text;
	my_vars.address = address_box.text;
	my_vars.csz = csz_box.text;
	my_vars.phone = phone_box.text;
	my_vars.fax = fax_box.text;
	my_vars.part = part_box.text;
	
	if (my_vars.sender != "" and my_vars.subject != "" and my_vars.part != "") {
		my_vars.sendAndLoad("http://kerneng.com/flash/mailer.php", my_vars, "POST");
		gotoAndStop(2);
	} else {
		error_clip.gotoAndPlay(2);
	}
	my_vars.onLoad = function() {
		gotoAndStop(3);
	};
};
email_box.onSetFocus = subject_box.onSetFocus=part_box.onSetFocus=function () {
	if (error_clip._currentframe != 1) {
		error_clip.gotoAndPlay(6);
	}
};

Heres the PHP Script, i'm trying to get content from

<?php

/* ---------------------------

Note: most servers require that one of the emails (sender or receiver) to be an email hosted by same server, 
so make sure your email (on last line of this file) is one hosted on same server.

// read the variables form the string, (this is not needed with some servers).
$subject = $_REQUEST["subject"];
$sender = $_REQUEST["sender"];
$name = $_REQUEST["name"];
$email = $_REQUEST["email"];
$company = $_REQUEST["company"];
$address = $_REQUEST["address"];
$csz = $_REQUEST["csz"];
$phone = $_REQUEST["phone"];
$fax = $_REQUEST["fax"];
$part = $_REQUEST["part"];



// include sender IP in the message.
$full_message = $_SERVER['REMOTE_ADDR'] . "\n\n" . '$name'. "\n\n" . '$email' . "\n\n" . '$company' . "\n\n" . '$address' . "\n\n" . '$csz' . "\n\n" . '$phone' . "\n\n" . '$fax' . "\n\n" .' $part'
$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 = $subject;

// send the email, make sure you replace [e-mail] with your email address
if(isset($message) and isset($subject) and isset($sender)){
	mail("[e-mail]", $subject, $message, "From: $sender");
}
?>
