DB Foundations Grouping Joining and Cleaning Up Challenge

Was doing OK with these queries but this one is killing me. Can't figure out what I'm missing:

Challenge Task 3 of 3

Like before, select the average "score" as "average", setting to 0 if null, by grouping the "movie_id" from the "reviews" table. Also, do an outer join on the "movies" table with its "id" column and display the movie "title" before the "average". Finally, include averages under 2.

Bummer! There's something wrong with your query.

SQL Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'GROUP BY movie_id HAVING average < 2' at line 1

What's weird is that part of the query is what works in task 2

my query:

SELECT title, IFNULL(AVG(score), 0) AS average FROM reviews LEFT OUTER JOIN movies GROUP BY movie_id HAVING average < 2;

missing something?
