Hi, @methodwhiz16864 ,

Because your code is not formatted, it is difficult for other users to read and debug it. As code is being posted, you can format it by selecting it, and then by clicking the `</>` button above the editing area. This will enable us to see important details, such as the indentation and underscores.

The following may not be the only problem, but here you have created a list of strings, because you used quotes ...

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

That needs to be a list of the three dictionaries, as follows ...

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