```
CREATE TRIGGER update_orderline

AFTER INSERT OR UPDATE ON ORDERS

FOR EACH ROW

BEGIN

  INSERT INTO ORDERLINE(orderline_no, qty, order_no, product_no)

  VALUES (ol_no.nextval, :new.qty, :new.order_no, :new.product_no);

END;

```

I am trying to create a trigger that updates orderline table after a new record has been inserted into orders. But I get this error: 

```
Error(3,26): PLS-00049: bad bind variable 'NEW.QTY'

Error(3,51): PLS-00049: bad bind variable 'NEW.PRODUCT_NO'

```
