Hey Cody,

Your error is coming from adding much more than what the challenge asked for. The 2nd task only wants you to throw an error inside the function. It did not ask for the 'guard' or the variable or anything else. You will find that the challenges are very specific and very picky. So all you need is ...

func lend() throws {
  throw BookError.IncorrectTitle
}

Keep coding! :)
