Structs Help!

Hey!

When I run this i get the error: extraneous argument label 'percentage:' in call var taxes = item.calculateTaxes(percentage: 7.5)

I dont really understand what this is saying/why its happening?

Any help will be much appreciated

Thanks Harland

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))
    }

    // add the calculateTaxes method here
    // it should accept only one parameter named 'percentage' of type Double

}

var item = Expense(description: "HEY") 
item.amount = 100
var taxes = item.calculateTaxes(percentage: 7.5)

change the last line of your code to this

var taxes = item.calculateTaxes(7.5)
