Checking Get variable exists

[Mike]

Hello,
How do I check to see if a GET varaible exists?
This is giving me an error message.

if (isset !($_GET['id']))
{die('You must Have a Key to get in');
}

Thanks

How about:

if(!isset($_GET['id']))

well, is the error "you must have a key to get in"?

just tac this onto the end your the url:

?id=qwerty

you shouldn't get that error at that point. do you understand the difference
between $_GET, $_POST, $_REQUEST?
