Uploading email form to hosting server

This is the HTML code

<div id="Footer">
<table width="391" height="40" border="0" cellpadding="1" cellspacing="1">
<tr>
<th height="38" scope="col"><table width="955" height="34" border="0" align="left" cellpadding="1" cellspacing="1">
<tr>
<th width="36" align="right" scope="col"><a href="http://www.facebook.com/update_security_info.php?wizard=1#!/profile.php?id=100001899947625"><img src="Images/facebook_widget.JPG" alt="facebook" width="26" height="26" hspace="5" border="0" /></a></th>
<th width="32" scope="col"><a href="http://twitter.com/#!/Jdesignworld"><img src="Images/Twitter_widget.JPG" alt="twitter" width="32" height="26" border="0" /></a></th>
<th width="58" scope="col"><a href="http://www.youtube.com/user/JDesignWorld"><img src="Images/youtube_widget.JPG" alt="youtube" width="57" height="26" border="0" /></a></th>
<th width="816" scope="col">Copyright @ JDesignWorld! All rights reserved</th>
</tr>
</table></th>
</tr>
</table>
</div>




and PHP code

<?php


$to = "jdesignworld@hotmail.com"; //This is the email address you want to send the email to
$subject_prefix = ""; //Use this if you want to have a prefix before the subject

if(!isset($_GET['action']))
{
die("You must not access this page directly!"); //Just to stop people from visiting contact.php normally
}

/* Now lets trim up the input before sending it */

$name = trim($_GET['name']); //The senders name
$email = trim($_GET['email']); //The senders email address
$subject = trim($_GET['subject']); //The senders subject
$message = trim($_GET['msg']); //The senders message

mail($to,$subject,$message,"From: ".$email.""); //a very simple send
echo 'contactarea|Thank you '.$name.', your email has been sent.';

?>

I ment contact form. This is a contact form.

I uploaded it to the server and all but it's not letting me send email. So I am wondering if somehow it's not connected?
