Help please

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 an id of 6. Movie ids are stored in the movie_id column. Calculate the minimum and maximum ratings for "Starman". Alias them as star_min and star_max.

SELECT MIN(rating) AS star_min , MAX(rating) AS star_max FROM reviews WHERE id = 6;

:point_right: You're using the wrong column name.

The challenge said: "Movie ids are stored in the movie_id column."

But instead of "movie_id", your WHERE clause uses just "id".
