I'm not quite sure what I'm doing wrong.

I tried initially with:

SELECT DISTINCT (genre), COUNT (genre) AS genre_count 
     FROM books
     ORDER BY genre;

but then i noticed the blank row under the genre section so i tried it again with the code that is attached that doesn't count the NULL row. What else am I doing wrong?

nevermind, i figured it out. What it should've been:

SELECT genre, COUNT(*) AS genre_count FROM books GROUP BY genre;

i forgot that the COUNT(*) with the asterisk means it uses the entire database to count with.
