this is an easy but hard fix.
If you are using the session_register("name"); You need to upgrade it to the $_SESSION['name'] = "1";. that is if you built the site yourself. if this is a packaged software you might have to see if they have an updated version. if you get stuck let me know, i just figured how to change my site

Actually it should be $_SESSION['name'] = $name which is the equivalent of what session_register('name') does. If you do ="1" then it will be 1 and not what was intended.

got me again.

well it was just an example i thought he would beable to figure it out

Thanks for the quick responses! Yes it is a package script but I guess I can go through it and change it. So does each of the following instances need to be changed?

session_start();
session_register("id_session");
session_register("password_session");
session_register("name_session");
session_register("address_session");
session_register("city_session");
session_register("state_session");
session_register("zip_session");
session_register("country_session");
session_register("phone_session");
session_register("email_session");
session_register("paymentoption_session");
session_register("refby_session");
session_register("l1_session");
session_register("l2_session");
session_register("l3_session");
session_register("l4_session");
session_register("l5_session");
session_register("l6_session");
session_register("l7_session");
session_register("l8_session");
session_register("l9_session");
session_register("l10_session");
session_register("total_session");
session_register("unpaid_session");
session_register("paid_session");

So this
session_register("id_session");
should be this:
$_SESSION['id_session'] = $id_session
etc? And would that then affect any of this:

$id_session=$_SESSION[id_session];
$password_session=$_SESSION["password_session"];
$rs=mysql_query("Select * from members where ID='$id_session'");
$arr=mysql_fetch_array($rs);
$pass=$arr[9];
$id=$arr[0];

if ($_SESSION["id_session"]!="$id" || $_SESSION["password_session"]!="$pass")
