Struct Methods - Challenge 3 of 4

Not sure what is wrong with the code. The compiler shows the following error: "return from intializer without initializing all stored properties"

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

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

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

var item = Expense(description: "Anything")
item.amount = 100

For me it Looks like you forgot to init the amount?!!

struct Expense {
    var description: String
    var amount: Double

    init (description: String, amount: Double) {
        self.description = description  
        self.amount = amount
}
