wildteen88 Posted March 14, 2006 Share Posted March 14, 2006 You might want to change any instances of [b]$pgnodes;[/b] to [b]$_GET['pgnodes'];[/b] as you're using pgnodes; to get the variable value form the url which is incorrect as you dont have register_globals turned on. Instead you have it turned off which it should!When you have register_globals turned off you have to use the superglobal arrays found [a href=\"http://uk.php.net/manual/en/language.variables.predefined.php\" target=\"_blank\"]here[/a].
