Your code isn't quite what the assignment is asking for. Say you have the number 15 and the divisors {2 => "Rawr", 3 => "Fizz", 5 => "Buzz" }. The return for your method would be "2FizzBuzz" when it should just be "FizzBuzz". You only want to return the number itself if the number is not divisible by *any* of the numbers from the hash of divisors.

Keep at it and resubmit! :3
