Need help on how to finish the challenge.

Got lost.

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)

  var item = Expense(description: )

  } 

}

You forgot to close your "func calculateTaxes" with a "}" before declaring item and the item you declared, doesn't have any string as an argument. (You have to have some string, since there's description of type String inside your struct's init) This is everything you need to do up to challange#3, although you need to be more specific in your question if you need something more helpful.

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))
    }

}

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