"How's everyone doing?" Something missing or broken?

#1

I keep getting this:
“Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade”

But I get this as an out put:
“B
83.8666666667
B
None”

I feel like I am close but just can’t figure it on it.

Hi @coreninja7587,

This statement should not have quotes around the names of the three dictionaries in the `list`

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

Yes that is it! Wow, I should have known. Thank you!
