Hi Mark. There are a few things that we need to change. Since the challenge doesn't need us to put a for in loop, we can take that out. Next, we need to change all the print statements to return statements. Finally, we don't need to print/return anything besides Fizz, Buzz and FizzBuzz. Therefore, let's get rid of the "n" print statement and change the conditional before return "Buzz" to else. The reason we don't need to put n % 5 is because it's implied the value is divisible by 5 without a remainder. This is due to the previous statements not evaluating to true. The final code should be:

func fizzBuzz(n: Int) -> String { // Enter your code between the two comment markers

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

// End code return "(n)" }

Hope this helped. ;)

Thank you for your detailed explanation!
