I got a little problem. When I got my PHP script without header it's fine, I am getting javascript alert box. But when I use header before alert it's not working. It's redirecting me like it should, but it's not showing any box. Could someone help me?

```
if ( $pkt < 1 OR $user_id == 0) {
    header("Location: http://dunno.com/file.php");
    $message = 'This is a message.';

echo "<SCRIPT> //not showing me this
alert('$message');
</SCRIPT>";
    mysql_close();
}

```

And here's the one which work (but without heading)

```
if ( $pkt < 1 OR $user_id == 0) {
    $message = 'This is a message.';

echo "<SCRIPT> //showing me
alert('$message');
</SCRIPT>";
    mysql_close();
}

```

I would be thankful for help :)

@edit Maybe is there any command to make alert wait until whole browser load? (if it's the problem)
