Challenge Task 2 of 4

Not sure what I'm doing wrong here.. nor how to move on

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

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) {
    return (self.amount*(percentage/100))
}

}

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

    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) {
        return (self.amount*(percentage/100))
    }

}

Hi there,

Your method also returns something so your method signature needs to include that returned value type:

func calculateTaxes (percentage: Double) -> Double{

I hope that helps.

Steve.
