Create Trigger to insert records from one table to another

Question

I created the below trigger to move data from one table to another after records have been inserted from another table to that table. What I need done is that each time records have been inserted into TEST_TBL, one of these actions codes should be implimented: U-update, N-insert, D-delete and inserted into TEST_TBL1. But each time I run the script, I get bunch of errors. Please see the script below: - Your help will be appreciated.
create or replace
trigger POWER_tr
after update or insert or delete ON test_tbl
for each row
begin
if updating then
insert into test_tbl1
(idx, mke, ctl, ori, nam, sex, rac, pob, dob, hgt, action_code, date_added
VALUES
(idx, mke, ctl, ori, nam, sex, rac, pob, dob, hgt, 'U', sysdate);
ELSif INSERTING then
insert insert into test_tbl1
(idx, mke, ctl, ori, nam, sex, rac, pob, dob, hgt, action_code, date_added
VALUES
(idx, mke, ctl, ori, nam, sex, rac, pob, dob, hgt, 'N', sysdate);
ELSIF deleting then
insert into test_tbl1
(idx, mke, ctl, ori, nam, sex, rac, pob, dob, hgt, action_code, date_added
VALUES
(idx, mke, ctl, ori, nam, sex, rac, pob, dob, hgt, 'D', sysdate);
END IF;
END POWER_tr;
Thank you,

Hello
At the end of trigger show errors / and post what errors are you getting exactly?
Here is a simple example for your reference, this will save old values in history table; you can replace it with new values if that's what do you want.
CREATE OR REPLACE TRIGGER TRG_DU
   AFTER DELETE OR UPDATE
   ON EMPLOYEE    REFERENCING NEW AS New OLD AS Old
   FOR EACH ROW
DECLARE
BEGIN
   IF UPDATING
   THEN
      INSERT INTO employee_hist
        VALUES   ('UPDATE',
                  :OLD.empid,
                  :OLD.name,
                  :OLD.deptid);
   ELSIF DELETING
   THEN
      INSERT INTO employee_hist
        VALUES   ('UPDATE',
                  :OLD.empid,
                  :OLD.name,
                  :OLD.deptid);
   END IF;
EXCEPTION
   WHEN OTHERS
   THEN
      -- Consider logging the error and then re-raise
      RAISE;
END TRG_DU;
