Expense.description

I don't know how to pass this one. If you guys could help me that would be great.

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

    init (description: String, amount: Double) {
        self.description = "Macbook"
        self.amount = 100

    }

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

var item = Expense.description

When creating your var 'item' you must specify the same parameters as in your initializer. In this case, 'description' or it won't work. This completes the 'instance' properly. Then set your amount = 100 as done below:

var item = Expense(description: "enter anything here") item.amount = 100

sorry

item.amount = 100 should be on the next line below!
