title: Having trouble with conditionals
body: <p>I'm trying to define a method that returns "fizz" when the integer is divisible by 3, "buzz" when is divisible by 5 and "fuzzbuzz" when the number is divisible by both. I know 15 is divisible by both, however I don't know what I'm inputting wrong in my code. Thank you. </p>
  
  <pre><code>def fizzbuzz(int)
    if int % 3 == 0
      return "Fizz"
    elsif int % 5 == 0
      return "Buzz"
    elsif int % 15 == 15
      return "FizzBuzz"
    else
    end
  end
  </code></pre>
