SQL HELP-ORA-04073 column list not valid for this trigger type

Hi,

After trying to create this trigger:

CREATE OR REPLACE TRIGGER a
AFTER INSERT OF duration, startdate ON route, outing
FOR EACH ROW
WHEN (NEW.startdate LIKE %jan%)
AND (NEW.duration = 5)
DECLARE
closed_in_jan EXCEPTION;

EXCEPTION
WHEN closed_in_jan THEN
RAISE_APPLICATION_ERROR (-20101,We are closed in January.');



I get this error:

ORA-04073 column list not valid for this trigger type
Cause
A column list was specified for a non-update trigger type.

Action
Remove the column list.


I've tried researching but can't find out what a column list is!

Any help would be appreciated, thanks.
