assigning a value to the amount property in the following task

I've tried several different ways of assigning this value to item. Some how I continue to get an error, where am I going wrong? here's my code

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(description: "Hotel")
item.amount = 100

}

try modeling it exactly like this

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(description: "Hotel")
item.amount = 100.0

Make sure to put var item outside the struct and item.amount = 100.0 with a decimal at the end to make it a Double
