I am trying to do pop up message on the same page.

```
$db->UpdateAddress($_POST['Cnum'],$_POST['Address']);
     echo "Address changed sucssefully";

```

i try to use this to display the popup but,the pop up is in blank page.

```
  $db->UpdateEmail($_POST['Cnum'],$_POST['mail']);
     $message = "E-mail changed sucssefully";
echo "<script type='text/javascript'>alert('$message');</script>";

```

thanks
