Can someone explain what this challenge wants?

https://teamtreehouse.com/library/reporting-with-sql/aggregate-and-numeric-functions/summing-values

I am British and English is my first language, however the query that gets the output which is the total of all ratings is not the right output as a where clause is needed, if someone could help me out with this I would really appreciate this.

select sum(rating) as starman_total_ratings from reviews;

Here's the code

There's a hint when the instructions say "The movie "Starman" has the id of 6." and "Movie ids are found in the movie_id column in the reviews table."

But it what they really want might not be totally clear when they say "Write a query that totals up all ratings in the reviews table."

Perhaps the instructions should be: "Write a query that totals up all ratings for the movie "Starman" in the reviews table." Try combining that with the previous 2 hints and see if you get it.
