Can't figure exactly what I am doing wrong here.

I felt I had it right until I received an error message so I looked on forums to see if I had done something wrong and it looked right to me. Any mistakes I might have missed.

struct.swift 
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)
   }
    }

    // add the calculateTaxes method here
    // it should accept only one parameter named 'percentage' of type Double

}

Hey Dylan, the func shouldn't be inside the init method. Just move your bracket...

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

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

Ok. Thank you. I was getting very frustrated after a while on that one. You were a big help.
