Check the answer and let me know why it is not right?

struct Book {
    let title: String
    let author: String
    let price: Double

let myBook = Book(title: "Animal Farm", author: "George Orwell", price: "6:00") 

// Enter your code below

Hey Haitham,

You've pretty much got it. It's just 2 small things: A minor syntax error and a minor typo.

When you set the 6.00 for the price, you used a : (colon) instead of a . (period). And, when you are setting a Integer or a Double, you don't use quotation marks. When you surround the value in quotation marks, you are making it into a string. So, remove the quotes and change the : and you're good to go:

let myBook = Book(title: "Animal Farm", author: "George Orwell", price: 6.00)
