Delete the rows if the check box is selected.

Question

Dear all,
i have a block (not database block). i added a check box to the same block. now i want to delete the row against which the check box is selected.
i wrote the following code in when-button-pressed trigger.
IF Checkbox_Checked('CHK_DEL') THEN
     delete from fa_01_11
     where as_id = :as_id;
END IF;
commit;
but when i select only one check box it delete the all rows from the table if the condition is satisfied.
here is the data in my table
as_id year month
63     2006     4     0     -1183.92     1
63     2006     5     0     -1183.92     1
63     2006     6     0     -1183.92     1
63     2006     7     0     -1183.92     1
63     2006     8     0     -1183.92     1
63     2006     9     0     -1183.92     1
63     2006     10     0     -1183.92     1
63     2006     11     0     -1183.92     1
63     2006     12     0     -1183.92     1
what's the proble?

You need to run the code for each record and you need to find something which is unique. as_id is not unique.
untested:
declare
  last_rec boolean := false;
  deleted boolean := false;
begin
  first_record;
  loop
    deleted := false;
    last_rec := :system.last_record = 'TRUE';
    IF Checkbox_Checked('CHK_DEL') THEN
      delete from fa_01_11
        where as_id = :as_id
        and year = :year
        and month = :month;
      clear_record;
      deleted := true;
    END IF;
    exit when last_rec;
    if not deleted then
      next_record;
    end if;
  end loop;
  commit;
end;
