Can you provide a link to the quiz/challenge/source material you have a question about? That way I can better understand how to help you.

Your answer looks an awful lot like what I got to pass a while back with the exception of yours being an inner join. I had to strip out table aliasing and use their full names throughout the query to get it to pass. I've put my code below as well as yours with stripped aliases so you can copy it to see if it passes (right now when I check work it hangs and then throws an error).

Yours:

select *
from Media
inner join Media_Genres
    on Media.media_id = Media_Genres.media_id
inner join Genres
    on Genres.genre_id = Media_Genres.genre_id
where Media.media_id=3;

Mine:

SELECT *
FROM Media
JOIN Media_Genres
    ON Media_Genres.media_id = Media.media_id
JOIN Genres
    ON Media_Genres.genre_id = Genres.genre_id
WHERE Media.media_id = 3;

Edit: Checked again now that my internet is stable and it appears to pass. So the only issue with your code was table aliasing which isn't really an issue but more of a limitation of Treehouse.
