iOS Swift Enums and Structs Structs and their Methods Struct Methods

Something is fried with my calculateTaxes method. When calling it, swift is not prompting for a Double, as expected

Does a fun behave differently when embedded in a struct?

struct.swift 
struct Expense {
    var description: String
    var amount: Double = 100.0

    init (description: String) {
        self.description = description
    }

    // add the calculateTaxes method here
    // it should accept only one parameter named 'percentage' of type Double
    func calculateTaxes (percentage: Double) -> Double {
        return (self.amount * (percentage/100))
        }
}
var item = Expense (description: "Big Tax")
let amount = 100.0

When you assign amount the value of 100 you need to use dot syntax(e.g. title.amount = 100) instead of assigning amount as a constant
