Hello all, I'm trying to build a forum site. The code below works fine but I dont know how to catch it from the address bar. I'm having trouble finding tutorials to help me with this.

viewtopics.php

echo "<tr bgcolor='#6698FF' ><td><a href='viewcomments.php?id=".$rows['topic']."'>
".$rows['topic']."</a></td><td>".$rows['username']."</td><td>".$rows['timestamp']."</td></tr>";

Address Bar

http://localhost/testsite/viewcomments.php?id=Cowboys%20Dancehall

I'm trying to use this in code below in viewcomments.php to retrieve the address info

$id = $HTTP_GET_VARS['topic'];

I'm getting this error
"Notice: Undefined variable: HTTP_GET_VARS in C:\wamp\www\testsite\viewcomments.php"

EEK! Which version of PHP are you using? I thought HTTP_GET_VARS was T_REX's extinct cousin.
