Email Subscription not showing name and email

Hi,

I am having a problem with this simple form and I can't see why the email is not showing the name and email fields.

The email goes through fine and is recieved but just does not show the name and email field.

Any thoughts?

Thanks

<?php
$field_name = $_POST['cf_name'];
$field_email = $_POST['cf_email'];


$mail_to = '';
$subject = 'Email List Subscription from Toycraft visitor -  '.$field_name;


$body_message = 'From: '.$field_name."\n";
$body_message .= 'E-mail: '.$field_email."\n";


$headers = 'From: '.$field_name."\r\n";
$headers .= 'Reply-To: '.$field_email."\r\n";


$mail_status = mail($mail_to, $subject, $body_message, $headers);


if ($mail_status) { ?>
<script language="javascript" type="text/javascript">
alert('Thank you for your subscription.');
window.location = 'index.php';
</script>
<?php
}
else { ?>
<script language="javascript" type="text/javascript">
alert('Message failed. Please, send an email to studio@');
window.location = 'index.php';
</script>
<?php
}
?>
