Hello Frank,

Rather than just throw you the answer, let me guide you thru it:

One of the possible solutions is to use a simple IF statement. Since the IF statement executes until one condition is true, make sure to start with FizzBuzz (a number divisible by 3 and 5):

    if fizzNumber % 3 == 0 && fizzNumber % 5 == 0 {
        print("FizzBuzz")
    } else if fizzNumber % 3 == 0 {
        print("Fizz")
    } else if fizzNumber % 5 == 0 {
        print("Buzz")
    } else {
        print("Is not a FizzBuzz number")
    }

Now I understand the test directions are confusing, it seems the only current way for Treehouse to check your answer is by altering your syntax. Basically replaced "print" with "return" and "fizzNumber" with "n". As removed the default (else if) statement. This is confusing, but it's the only way they can actually validate your code.

     if n % 3 == 0 && n % 5 == 0 {
        return("FizzBuzz")
    } else if n % 3 == 0 {
        return("Fizz")
    } else if n % 5 == 0 {
        return("Buzz")
    }

Thank you very much @mfagency . I thought I understood the question but I was unable to confirm the answer. I realize my return statements were incorrect. I did not have parenthesis when returning my strings. I must of been assuming the return statement would be similar to javascript javascript since we did not see one during this entire course. The instructions even display the return statement without the brackets lol.
