Trigger created with errors

Question

Hi All,
I have created a new trigger but it has compilation errors, I get the error which says SQL command not properly ended when look up in toad.Can you please advise what's wrong in my syntax below.
Also ,inorder for me to rollback the trigger I just created do I need to drop that trigger and run the create or replace trigger statement or the create or replace statement will replace the previous trigger that I created.
Thanks !
create or replace TRIGGER Abcd.lddp_tup
BEFORE UPDATE ON lddp FOR EACH ROW
declare timenow TIMESTAMP;
begin
SELECT CURRENT_TIMESTAMP INTO timenow FROM DUAL
:new.create_sid := :old.create_sid;
:new.create_date := :old.create_date;
:new.saved_date := timenow;
:new.par_num := :old.par_num;
:new.af_id := :old.af_id;
IF
:new.locked_bemsid IS NOT NULL AND :old.locked_sid IS NULL
THEN
:new.locked_date := timenow;
ELSE
:new.locked_sid := :old.locked_sid;
:new.locked_date := :old.locked_date;
END IF;
end;

Hi ,
can you be more specific how that statement should be altered?can you spell PL/SQL without assistance?
CREATE OR replace TRIGGER abcd.lddp_tup
  before UPDATE ON lddp
  FOR each ROW
DECLARE
    timenow TIMESTAMP;
BEGIN
    timenow := current_timestamp;
    :new.create_sid := :old.create_sid;
    :new.create_date := :old.create_date;
    :new.saved_date := timenow;
    :new.par_num := :old.par_num;
    :new.af_id := :old.af_id;
    IF :new.locked_bemsid IS NOT NULL
       AND :old.locked_sid IS NULL THEN
      :new.locked_date := timenow;
