if you have more than one var in the URL, it has to be formatted like this:

index.php?var1=foo&var2=somethingelse&var3=what

that would result in

$_REQUEST['var1'] == 'foo';
$_REQUEST['var2'] == 'somethingelse';
$_REQUEST['var3'] == 'what';

Also, for security reasons, make sure to either use the vBulletin function globalise() or to addslashes() anything that gets used in a query. If the value is a number, you can also do intval().
