使用以下触发器时出现错误：

create or replace trigger t1
  after insert or update  
     on student_tbl 
  declare
   pragma autonomous_transaction;
    begin
   if inserting then

 insert into stud_fees_details(stud_id,fees_balance,total_fees) 
       select stud_id,course_fees,course_fees from student_tbl s,courses_tbl c where s.stud_standard_id=c.course_id;

 elsif updating('stud_standard_id') then

insert into stud_fees_details(stud_id,fees_balance,total_fees) 
select stud_id,course_fees,course_fees from student_tbl s,courses_tbl c where s.stud_standard_id=c.course_id;

 end if;
end;

错误是
