Page Restriction - Authorization Scheme

Question

I have an application 8736 this application as 3 tabs
TAB1: information  TAB2: department   TAB3: Admin
TAB3 as a form in which SHOULD be only be view by users which authorisation rights. I have been trying to do this for sometimes now and it is not work. I have a table called users
TABLE:users
username    access_level      
john919             2
sarah765           0
For the page in TAB3 if you have an access level of 2. You should be able to view this page and if not they you should get an error message saying "sorry you cant view this page".
In this case "john919" should be able to view the page in tab "Tab3" and "sarah765 " SHOULD NOT.
I have this query in the Authorization Scheme and the scheme type: pl/sql function returning boolean
DECLARE
   v_access_level   NUMBER (2);
BEGIN
   IF (:APP_PAGE_ID = 61)
   THEN
      SELECT MAX (ADMIN_LEVEL)
        INTO v_access_level
        FROM USERS
       WHERE USER_NAME = :APP_USER;
      IF v_access_level = 2
      THEN
         RETURN TRUE;
      ELSE
         RETURN FALSE;
      END IF;
   ELSE
      RETURN TRUE;
   END IF;
END
I have never try this before and I have being asking around and alot of people tell me this should check the admin_level in the USERS table using the current username of the person looking in to see if they have access to this page. SO far this is as fail me. Please help

If you only have one access level per user then try changing your authorization scheme code to
DECLARE
   v_access_level   NUMBER (2);
BEGIN
      SELECT ADMIN_LEVEL
        INTO v_access_level
        FROM USERS
       WHERE USER_NAME = :APP_USER;
      IF v_access_level = 2
      THEN
         RETURN TRUE;
      ELSE
         RETURN FALSE;
      END IF;
END;
now apply this scheme to tab3
