Passing message from plsql code to page

Question

Hello Everybody,
I am trying to pass a 'success message' from plsql code which runs on page processing to the page. This plsql is a insert statement and if statement runs successfully (on submit) then I want to show a success message on the page after summit.
Your comment and help would be appreciated.
Thanks,
Raj.

Thank you Tony.
Stored Procedure which I am calling on the page is running in database. So if this procedure runs successfully(or vice versa), how I would know?? Is there a way to pass value from database stored procedure to it's calling page?
Following is procedure:
procedure load_stateday_result(key_loc ATM_STATE_DAY_INSP.KEY_LOCATION%type) is
temp_key_insp ATM_INSPECTION.KEY_ATM_INSPECTION%type;
temp_key_location number(8);
temp_dte_schedule date;
begin
temp_key_location := key_loc;
select key_atm_inspection,dte_schedule into temp_key_insp, temp_dte_schedule
from atm_inspection where
key_location = temp_key_location and exam_type = 'D' and exam_yr = to_char(sysdate,'yyyy');
insert into atm_state_day_insp(key_atm_state_day_insp,key_location,key_atm_insp,scheduled_dte)
values(state_day_insp_seq.nextval,key_loc,temp_key_insp,temp_dte_schedule);
COMMIT;
EXCEPTION
WHEN OTHERS THEN
dbms_output.put_line('Error :'|| SQLCODE||':'||SQLERRM);
--ROLLBACK;
RAISE;
end load_stateday_result;
Will appreciate your reply.
Thanks,
