Can anyone help me to amend the SQL below?

Question

I do not know how to implement roles application in the Oracle Forms, so I have tried to use the below SQL to tackle this problem. The code below can be compiled successfull but its application of open form () cannot work. Can anyone help ?
DECLARE
rg_id RECORDGROUP;
rg_name VARCHAR2(30);
ret_code NUMBER;
BEGIN
rg_name := 'RG_LIST';
rg_id := FIND_GROUP(rg_name);
IF NOT ID_NULL(rg_id) THEN
DELETE_GROUP(rg_id);
END IF;
rg_id :=CREATE_GROUP_FROM_QUERY( rg_name,'SELECT PASSWORD, into
password_value FROM STAFF WHERE STAFF.LOGIN_ID =:LOGIN.LOGIN_ID');
ret_code := POPULATE_GROUP( rg_id );
--IF (ret_code <> 0) THEN
-- Message ('no such user');
-- RAISE FORM_TRIGGER_FAILURE;
--END IF;
if (:Login.password =
Get_Group_Char_Cell(rg_name||'password_value',1)) THEN
open_form('trans_tab');
end if;
end;

Note that you may have more luck posting this sort of Forms-specific question in the Oracle Forms group.
