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

#2

It's saying one of a couple of names is missing or has an incorrect value. Have you tried printing out those names? It's not a mystery when it says what's wrong!

#3

I still dont get it!

#4

If I tell you one of five things are missing.. Then you can figure out which one it is by looking for each one of those 5 things. Which one is missing will be clear from which one can't be found.

So print them out.
