First, I'm going to try with some hints. And we'll see if you can get it done :smiley: Part of the problem here lies in the requirements of the challenge. While your code might be functional outside the challenge it won't work here. A switch statement requires a default. And the challenge instructions say this:

Do not worry about the default case (where the number doesn't match Fizz, Buzz, or FizzBuzz). The code in the challenge editor already takes care of that by returning the number as a string using string interpolation.

So this entire thing should be written as if and else if statements.

Also, this challenge specifically says that you should not print anything. All of these strings are to be returned:

Change all your print statements to return statements. For example: print("FizzBuzz") becomes return "FizzBuzz".

Give this another shot with these tips in mind! :sparkles:
