[F8] Send vars to PHP

[Gemione]

I have the following in my F8 AS 2.0:

getURL("email.php?sName=" + _root.form.contactName.text +
               "&subject=" + _root.form.contactSubject.getSelectedItem().data +
               "&email=" + _root.form.contactEmail.text +
               "&message=" + _root.form.contactEmail.text,"_blank","POST"); 

and this in my php:

$name = $_POST['sName'];
    $email = $_POST['email'];
    $subject = $_POST['subject'];
    $message = $_POST['message"']; 

but when I echo teh variable names, I get noghing.
