Please what is wrong with my code ?

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

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

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

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

}

By taking a quick look I've noticed that you are creating the var "item" inside the struct. As you are creating an instance of the struct Expense you should create it outside instead.

Hope that helps

Thanks Francisco Navarro,

The code should be

 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 ))
   }
}

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