Help on structs

Challenge Task 2 of 4, can't find out what's wrong here.

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

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

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

Here's what's wrong. Your method is supposed to return a Double but you didn't write the "return" word before (self.amount * (percentage/100)). Just add the "return" word and you"ll be good. It has to look like that with: '''html<p> 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)) } }</p>'''
