Hey I am trying to create a trigger for a table so that when I update or add a record on my invoice line table, it will automatically calculate the new line total. Thought I had to code right, but something is wrong. Can anyone help me?

The code for my trigger is:

CREATE OR REPLACE TRIGGER LINE_TOTAL_T
BEFORE INSERT ON LINE
FOR EACH ROW
BEGIN
NEW.LINE_TOTAL:= :NEW.LINE_UNITS * :NEW.LINE_PRICE;
END;


The errors displaying are:
LINE/COL ERROR
2/2 PL/SQL: Statement ignored
2/2 PLS-00201: identifier 'NEW.LINE_TOTAL' must be declared


Any thoughts??

Thanks!

Never mind! I was missing a silly colon in front of new.line_total.
thanks
