Hi Michael,

If you put quotation marks for your variable "rating", it means you want to store the value as a String. In the code challenge, they want the rating to be stored as a Double. To pass it, you just have to give up the quotation marks.

Here is the code:

let title = "A dance with dragons"
var rating = 7.5
