How to Create a Trigger

Question

I am using Oracle SQL Developer Data Modeler, and am looking to create insert triggers. How do I fill out the Trigger Properties window? For instance, when a value is entered on table 1, but its not an option on table 2, I want the trigger to insert "NA". How is this done?
Thanks! Any help is appreciated!

This might be a better question to ask in the SQL*Developer forum. You can find it under
Development Tools
+ Application Development in PL/SQL
on the site menu.
I personally write SQL*PLUS scripts to create triggers so I automatically have an offline copy as a back-up if needed later, something like (untested)
CREATE OR REPLACE TRIGGER my_trigger
after INSERT my_table
FOR EACH ROW
BEGIN
  insert into my_table2(
    column1
  values(
  'value1'
END;
