Multiple criteria ORDER BY clause

My assignment requires multiple ORDER BY clauses but I'm not sure what I did wrong here.

SELECT * FROM phone_book ORDER BY last_name ASC, ORDER BY first_name ASC;

When combining ordering criteria, just separate them with commas.

So instead of this:

SELECT * FROM phone_book ORDER BY last_name ASC, ORDER BY first_name ASC;

You might write this:

SELECT * FROM phone_book ORDER BY last_name ASC, first_name ASC;

Also, "ASC" is the default so it may be omitted.
