When I type in the following code, it's saying that my code didn't yield the proper results. I can't understand why.

Here's my code. I'm pulling the Min and Max for only the movie called "Starman".

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

You were really close.

You just did a little too much. The challenge didn't ask for the movie_id to be shown.

Just remove that term from the SELECT list.

Ok thanks Steven. I just tried this and it's saying that my calculation is wrong.

SELECT MIN(rating) AS star_min, MAX(rating) AS star_max FROM reviews

Absolutely nothing that I'm trying is working. I even tried this: SELECT AVG(rating) AS average, MIN(rating) AS star_min, MAX(rating) AS star_max FROM reviews GROUP BY id;

But now you're forgetting the WHERE clause to filter on the movie_id. Your original code was good except that you did not need to SELECT the movie_id.

Oh, ok. I tried that but also deleted the WHERE clause too. So that's why it didn't work. But it worked now. aaaaaahhhh thank God! Thanks steven.
