I have run in to some sort of error, please let me know if it is user. My task is to join two columns, movies.title and genres.name, using an inner join, with titles being first. I have entered: SELECT movies.title, genres.name FROM movies INNER JOIN genres. This gets me the correct results, in the correct order in both workbench and the site-side engine. But the quiz says incorrect. Please Advise.

9,234 PointsYou're right but you need a little more. You've defined what will be shown and you've defined the inner join, but you haven't defined the relationship between the tables.
SELECT movies.title, genres.name FROM movies INNER JOIN genres ON movies.genre_id = genres.id;
The "ON" operator starts the relationship, and you then use the format [table1].[column1] = [table2].[column2] to declare the relationship.
He talks about this in the video around the 1 minute mark. I hope this is helpful to you.
