Summing Values

We're in a movie database. There's a reviews table with the columns of id, movie_id, username, review and rating. The movie "Starman" has the id of 6. Movie ids are found in the movie_id column in the reviews table. Write a query that totals up all ratings for the movie "Starman" in the reviews table. Alias it as starman_total_ratings. Type in your command below, then press Ctrl-Enter. SELECT SUM(rating) AS starman_total_rating FROM reviews WHERE id = 6;

Even though it states 'The movie "Starman" has the id of 6' it should be has a movie_id of 6. Also your alias is missing an 's'.
