In order to diagnose the problem you would obviously need to know exactly what you typed, otherwise all you can say is: "you did something wrong, but as you didn't tell us what you did, we can't tell you what it is that you did wrong", which would obviously be exceptionally unhelpful. So tell us _exactly_ what you did, that is, give us the code you used. -- Maarten ----------------------------------------- Maarten L.
