Calculation of sums is not correct -- Not sure what I'm doing!

You can see from the link here: https://teamtreehouse.com/library/reporting-with-sql/aggregate-and-numeric-functions/summing-values. This is the challenge I'm working on. I got really close, but then I kind of got confused and messed things up. Here is my code: 

SELECT SUM(review) AS starman_total_ratings FROM reviews WHERE movie_id = 6 GROUP BY rating ORDER BY starman_total_ratings;

Thanks in advance!

You still have a few issues, some might be over-complication as a result of frustration:

  • the challenge wants you to sum the rating but you summed review.
  • you won't need GROUP BY since you're only reporting the aggregate
  • you also won't need ORDER BY since you'll only be returning one item

Ah, thanks yet again! I'm 14 right now, so frustration comes a tad easier than some more code-learned people! I got it cleaned up and passed the task.

It's really great that you're getting into programming already (5 years earlier than me!). Happy coding!
