Hi, @violasftw ,

We cannot see the code for your `get_class_average` function in the illustration that you posted, but the message from Codecademy suggests that you tried to access a variable, `class_list`, that had not yet been defined.

See @bandit's message. It would be more practical for us to test your submission, if it were posted as formatted code. See How do I format code in my posts?.

I changed it with a formatted code

Ok I found the problem. For those with the same issue, i had

``def get_class_average(students)``

``def get_class_average(class_list)``
