Format Trigger not working in 10g Report.

Question

I have a report with two eclipses
(*) Debit (*) Credit . Please note that the two asterics denotes eclipses.
I have a format triggers on these eclipses based on the database item Debit_credit.
IF :debit_credit = 'CREDIT' THEN
RETURN FALSE;
ELSE
RETURN TRUE;
End if;
and vis-visa. However the format trigger is not working. Regardless of the value of
debit_credit. I even created a frame around these eclipses and put my format trigger all to no avail. Please help.

Answer 1

Create a boilerplate text in your repeating frame (get rid of the field :debit_credit from your layout, but leave it in your query). I created the boilerplate field B_1. My format trigger looks like:
function B_1FormatTrigger return boolean is
begin
  if upper(:debit_credit) = 'CREDIT' then
       srw.set_field(0, to_char('(*) CREDIT'));
   else srw.set_field(0, to_char('(*) DEBIT'));
  end if;
  return (TRUE);
end;I hope I understood your question OK...I am not sure what an eclipses is?
