When I try to Save and submite the code gives me this error "Something went wrong

Click Close to try again or refresh the page." I have already refreshed the page a lot of times but it gives me the same error.

Is it something with my code or is something else?

```
lloyd = {
"name": "Lloyd",
"homework": [90.0, 97.0, 75.0, 92.0],
"quizzes": [88.0, 40.0, 94.0],
"tests": [75.0, 90.0]
}
alice = {
"name": "Alice",
"homework": [100.0, 92.0, 98.0, 100.0],
"quizzes": [82.0, 83.0, 91.0],
"tests": [89.0, 97.0]
}
