$query="SELECT * FROM results WHERE autonumber = $_GET[id]";
When they goto the index page and click a result it would goto "results.php?id=1/2/3/"
And display the appropiate data.
My question is, how can i get the page to display "No data specified" or something similar when someone just types results.php with no ID. At the moment it will just show the page with the database driven areas blank.
