Task is to figure out which author has written over 1 million words. Here is what I wrote, and I'm pretty sure it is correct (I have also found other peoples answers on google and they match mine, but the next step is greyed out..)

SELECT author, SUM(words) AS total_words FROM books GROUP BY author;

SELECT author, SUM(words)
AS total_words
FROM books
GROUP BY author
HAVING total_words > 1000000

For Step 1 of the Wordiest Author Challenge, you only need one SELECT statement. Your second statement here looks correct, except it is missing the final ; Try deleting the first statement and see whether you pass Step 1.

Remember that the auto-grader looks for very specific code. If you want to experiment, write any additional code at the end of the challenge, after you have written all of the code to pass the challenge.
