Error tracing

Question

Consider the following scenario:
When_mouse_double_click procedure is calling Click_Save procedure which contains the do_key('commit_form') statement.
As a result of which key-commit trigger is fired. I am raising Form_Trigger_Failure exception from this trigger.
I want to know that in When_mouse_double_click procedure how can i check that an error has occurred in the key-commit trigger.
Following explains the procedure calling sequence:
When_mouse_double_click
Click_Save
key-commit
Raise exception
The error_code system variable is 0 in Click_Save and When_mouse_double_click procedures so it cannot help me
Exception when others then statement is also not helping me
I am using Forms10g with Oracle 10g

hi
try something like this.
key-commit trigger
DECLARE
FormErr   NUMBER;
dbErrNo   NUMBER;
dbErrTxt  VARCHAR2(200);
FormTxt   VARCHAR2(80);
ErrTyp    VARCHAR2(3) ;
BEGIN
  commit;
    FormErr := ERROR_CODE;
    IF FormErr = 40400 THEN
      -- get the database error and text
      dbErrNo := DBMS_ERROR_CODE;
      dbErrTxt := DBMS_ERROR_TEXT;
      -- display the real problem
      MESSAGE('ORA'||TO_CHAR(dbErrNo)||': '||dbErrTxt, ACKNOWLEDGE);
    ELSE
      -- get the form messages
      FormTxt := ERROR_TEXT;
      ErrTyp := ERROR_TYPE;
      -- show the complete form message and error
      MESSAGE(ErrTyp || '-' || TO_CHAR(FormErr) || ': ' || FormTxt);
    END IF;
    RAISE FORM_TRIGGER_FAILURE;
END;sarah
