[SOLVED] include

[unidox]

I have this include:

<? include("" . $site_url . "incs/files.inc.php?p=admin_users"); ?>

 

and this is admin_users:

case "admin_users":
if(($_SESSION['admin'] == 1) && ($_SESSION['level'] <= $level['users'])) {
?>
Admin Users.
<?
} else {
// Login Failed
echo "You dont have access";
}
break;

 

with the include, it doesnt read the session, and it says I dont have access, but if I go to the page like http://site.com/?p=admin_users it works fine. Whats wrong
