Please help I'm stuck!!

Create a variable named item and assign it an instance of Expense (remember to use the initializer with the description parameter. Enter any description you like). On the next line assign the amount property a value of 100.

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

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

var item = Expense(self.description: "Cool", self.amount: 100)

Hi Carlos,

The challenge wants the item's amount to be assigned on a separate line. Also, you won't need to use the self keyword for the description or amount: in both lines, it will be clear that you're assigning these values to properties of the item variable.

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

Hope this helps!
