SELECT SUM(rating) AS starman_total_rating FROM reviews WHERE movie_id = 6 this is wrong but sum is 10

the question is "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."

My code is "SELECT SUM(rating) AS starman_total_rating FROM reviews WHERE movie_id = 6;

The error is " Bummer! Your query didn't perform the correct sum calculation." However when I run the whole table all the rating with the movie_id of 6 add up to be 10, and that is the answer my code gives.

As you quoted them, the instructions ask for the column alias to be "starman_total_ratings" (plural), but your code has "starman_total_rating" (singular).

Ha ha ha. Thanks man I really appreciate that.
