I'm lost...Swift Enums and Strucs Challenge 2 of 4

I'm lost, thought i was going good. then I hit this road block. I'm sure with more experience I'll get the hang of it. I'm probably overthinking it!

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

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

    func calculateTaxes(percentage: Double) {
        var cal = self.amount * (self.calculateTaxes(0.0/10))
        return cal
    }
}

Your function needs to specify a return type. After the paremeter (percentage: Double) put -> Double

Something is also going wrong inside the function. You don't actually even need to create a variable. Just put "return" and then things they asked for, like this:

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

here's my code: 

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))
    }
}
