<Below this line, in what way does your code behave incorrectly? Include ALL error messages.>
Not sure what is wrong with what I have.
<In this course, it often helps to include a screenshot of your whole web browser – that lets everyone see what you see. If you wish to include a screenshot, add it below this line.>

<If you wish to copy/paste in your code, you can use this next section. This will allow others to copy/paste your code for testing – something that they won’t be able to do with just a screenshot.>

SELECT a.dep_month,
a.dep_day_of_week,
AVG(a.flight_distance) AS average_distance
FROM ( SELECT dep_month, dep_day_of_week, dep_date, AVG(distance) AS flight_distance
FROM flights
GROUP BY 1, 2, 3) a
GROUP BY 1, 2
ORDER BY 1, 2;

Replace this line with your code.
