How to disable selection of checkbox ?

Question

Hi,
I got the following query wrote under WHEN-ITEM-NEW-INSTANCE :-
Declare
In_routing_header_id number;
begin
select      rrh.routing_name,
     rrh.routing_header_id
into     :receipt_match.aic_routing_dsp,
     in_routing_header_id
from     po_line_locations_all plla,
     rcv_routing_headers rrh
where     rrh.routing_header_id = plla.receiving_routing_id
and     plla.line_location_id = :receipt_match.po_line_location_id;
if in_routing_header_id = 2 and :receipt_match.rect_qty_accepted = 0 then
set_item_property('receipt_match_control.receipt_match',enabled,property_false);
*** set_item_property ( 'receipt_match.selection_checkbox', enabled, property_false);
raise form_trigger_failure;
end if;
set_item_property('receipt_match_control.receipt_match',enabled,property_true);
end;
Please note on line *** where I inserted this line is to disable user from make selection/ click on the checkbox. However, I got the error when putting this. The error prompt : 'FRM-41032: Cannot set enabled attribute of current item XXXXX '
Please helps. I'm new in oracle forms.
Thanks

Hi,
Thanks for reply. However, I need to put the code only in the WHEN-NEW-RECORD-INSTANCE as the form that I called will display the data for user to check the button and select. I need to diable the check button from selection here. As you can see from the code, the match button had disable but now I need to disable the checkbox.
This is b'cos current status is even the match button has disable but the checkbox still can enable user to make mistake and record still can be saved from there. That's why I need to disable the checkbox to prevent user from make selection and saved.
Hope this is clear and looking forward to your helps.
