Grouping, Joining, and Cleaning Up Challenge 2 of 3 Bugged?

Stuck on this question. Here is my code:

SELECT movies.title, IFNULL(AVG(score),0) AS average FROM reviews RIGHT OUTER JOIN movies ON movies.id = reviews.movie_id GROUP BY movie_id HAVING average < 2;

Looking through the forums, it seems that others have passed this with similar or exact code. Is this bugged?

Michael;

Have you tried:

# Course: Database Foundations
# Module: SQL Calculating, Aggregating and Other Functions
# Challenge: Grouping, Joining, and Cleaning Up
# Task: 2 of 3


SELECT AVG(score) AS average FROM reviews GROUP BY movie_id HAVING average < 2;

Happy coding,

Ken

That did it. I clearly need to spend more time with the SQL documentation. Thanks!
