Create a variable named travel and assign it an instance of the Expense struct with the following values for each stored

here is my code:

``swift struct Expense { var description: String = "description" var amount: Double = 0.00 

   init(description :  String) {
    self.description = description
}
var travel = Expense(description: "Flight to Cupertino", amount: 500.00)

} `` and my error: error: swift_lint.swift:10:25: error: extra argument 'amount' in call var travel = Expense(description: "Flight to Cupertino", amount: 500.00)

struct.swift 
struct Expense {
    var description: String = "description"
    var amount: Double = 0.00       

       init(description :  String) {
        self.description = description
    }
    var travel = Expense(description: "Flight to Cupertino", amount: 500.00)
}

Hi Charles!

Your init method signature only has one parameter. You need to either 1. add another parameter to your method signature, or 2. set the amount property outside of calling init. Also, on the property/properties that are being set in init, there's no need to set a default value. I've made that change in the options below.

Option 1:

struct Expense {
    var description: String
    var amount: Double

       init(description :  String, amount: Double) {
        self.description = description
        self.amount = amount
    }
    var travel = Expense(description: "Flight to Cupertino", amount: 500.00)
}

Option 2:

struct Expense {
    var description: String
    var amount: Double = 0.00       

       init(description :  String) {
        self.description = description
    }
    var travel = Expense(description: "Flight to Cupertino")
    travel.amount = 500.00
}
