Ahh, you have a syntax error. See the }, you need to add ?> after it like this:
PHP Code:
<?php
$printingVar = 'Thank you for sending this message. I\'ll get to you soon.';
mail("shane@wncspacemakers.com",htmlentities($_POST['subject']), "Message from ". htmlentities($_POST['emailaddress']) ."\n". htmlentities($_POST['message']),'From: '. htmlentities($_POST['emailaddress']));
$email = "";
$subject = "";
$message = "";
}
?>
