Be sure you have grouped your query elements properly.

Remember that any filter condition that applies to individual rows will go in a WHERE clause, and come before a GROUP BY. And any filter that applies to the aggregate value(s) will go after it in a HAVING clause.

To enable a more specific and accurate analysis, always show your complete code and provide a link to the course page.

can you send me the query for the question please. We are in 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. Write a query that totals up all ratings in the reviews table. Alias it as starman_total_ratings.

Please give it your best "good faith" attempt, using the hints already given, and then post your code if you still need some help.
