Enums and structs step 2 of 2.. I'm having trouble with the answer..

i did var travel = Expense.description = "" and i dont think i can also do var tavel = Expense.amount = 500.00

I'm kind of stuck..

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


}

var travel = Expense.description = "Flight to Cupertino"

Hello Devin:

From what I can see, what you are trying to do is create an instance of “Expense”. 

struct Expense {
    var description: String // String type
    var amount: Double // Double type    
}

// Instance 

var travel = Expense(description: "Flight to Cupertino", amount: 250.00)

When creating an instance of a class or struct you have to call it by its name and its parameters. Since structs create their own initializers, you do not have to create one, just simple use its store properties as its parameters, and give them values according to their type.

Hope this helps
