Hi Ron,

The issue here is on this line in your HTML file: {% for course in courses[teacher] %} You're trying to get something out of a dict of courses, but it's never defined anywhere.

You were, however, pretty close! In the challenge description, it says that the teacher dict has a courses item in it. Try looping over that!

I hope I provided a good enough pointer like this, if you're still stuck, feel free to message me!

Regards, Jari
