Add a Double as a return type to the calculateTaxes method and within the method return the following expression: (self.

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)->Double{ return (self.amount * (percentage/100))

}

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

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

This is how it should look after the second part of the challenge:

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)
    }


}

Thank you am still getting an unresolved error

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