# 9/9 How is Everybody Doing?

#1

Hi there,

i stuck in the lesson. Got a output, it is right (i got the code after 1,5h), but i got a error message.
Please tell me what i do wrong. I go forward now, but i want to know whats happen.
Maybe something is missing, but why i got the correct output.
Thank you, i am new in coding

Error message:
One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade

<What do you expect to happen instead?>
83.8666666667
B # and the message in kind of :Yay go next and so on

Hi @ser_1of744000000,

You are missing this line from Exercise 3: Put It Together

``````students = [lloyd, alice, tyler]
``````

Though you have this line …

``````class_list = [lloyd, alice, tyler]
``````

… Codecademy’s submission correctness test (SCT) looks for the one you created in that earlier exercise.
