Error in a Trigger

Question

the below error occurs when I delete from tabular form. I created the trigger to Log the Updates , adds and delete of the Name from the Tabular form.
<code>
CREATE OR REPLACE TRIGGER log_trg
BEFORE INSERT OR DELETE OR UPDATE ON subjects FOR EACH ROW
DECLARE
l_type VARCHAR2(50);
case1 VARCHAR2(50);
BEGIN
select caseno into case1 from cases1 where id = :new.caseid;
IF inserting THEN
l_type := 'Added Name:';
INSERT INTO log(caseid,CASE,author,whendone,changes)
VALUES(:new.CASEID,CASE1,'Admin',SYSDATE,l_type||:NEW.subjECTNAME);
ELSIF updating THEN
l_type := 'Updated Name:';
INSERT INTO log(caseid,CASE,author,whendone,changes)
VALUES(:new.CASEID,CASE1,'Admin',SYSDATE,l_type||'"'||:old.subjECTNAME||'"'||' to '||'"'||:NEW.subjECTNAME||'"');
ELSIF deleting THEN
l_type := 'Deleted Name:';
INSERT INTO log(caseid,CASE,author,whendone,changes)
VALUES(:old.CASEID,CASE1,'Admin',SYSDATE,l_type);
END IF;
END;
</code>

I am still getting the below error even after having it as :old.caseid.
