Both of these answers are correct and will pass the challenge:

Answer explicitly stating the type.

let title: String = "A Dance with Dragons"
let price: Double = 9.99
let yearPublished: Int = 2011

Answer using type inference:

let title = "A Dance with Dragons"
let price = 9.99
let yearPublished = 2011

People I found the problem. You cant erase the previous line. Where it says to declare the title. It specifically says at the top to build on top of previous code. I did it. I worked perfect.
