Creating variable after a struct

Code compiles in Xcode, but won't in the exercise and isn't returning anything on the preview screen.

struct.swift 
struct Expense {
    var description: String
    var amount: Double = 0.0

    init (description: String, amount: Double) {
        self.description = description
        self.amount = amount
    }
    func calculateTaxes(percentage: Double) -> Double {
     return (self.amount * (percentage/100))
      }

    // add the calculateTaxes method here
    // it should accept only one parameter named 'percentage' of type Double
    }
 var item = Expense(description: "Doge", amount: 100)

Hi John,

Task 3 of this challenge doesn't want you to change the constructor, instead it wants you to create a new instance of the Expense struct however it wants you to set the amount of the next line by referencing your Expense instance.

var item = Expense(description: "Doge")
item.amount = 100

Happy coding!
