You didn't say, but it looks like you're working on task 2. Here's a few hints:

  • the instructions ask for an alias of "total_genres" (with an underscore) instead of "total genres"
  • you won't need GROUP BY for this task
  • you only need to select the count, not the "genre" column
  • only count the distinct genres
