When I test this contact form php script, I get email and only message. I have not got there email or subject. What is wrong?

<?php

$emailsubject = 'Message from Contactus';
$webmaster = 'tyla1@live.com';

$name = $_post['name'];
$subject = $_post['subject'];
$email = $_post['email'];
$message = $_POST['message'];

$body = <<<EOD
Email: $email 
Name: $name 
Subject: $subject 
Message: $message
EOD;

$headers = "From: $email\r\n";
$hearers .= "Content-type: text/html\r\n";
$success = mail($webmaster, $emailsubject, $body, $headers);
echo "<script language='JavaScript'>alert('Thank you');window.location= 'index.php';</script>";die;
?>

typo on headers variable.

 

$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'To: Your Name <'.$webmaster.'>' . "\r\n";
$headers .= 'From: '.$name.' <'.$email.'>' . "\r\n";

Still not work
