struct help

i need to :

Create a variable named item and assign it an instance of Expense (remember to use the initializer with the description parameter. Enter any description you like). On the next line assign the amount property a value of 100.

my code looks like this :

struct.swift
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:"Anything")
    item.amount=100.00
}

Whats wrong with what I'm doing ? Thank you.

That's all fine. One small thing ;-) ... move the last two lines of code outside of the struct:

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:"Anything")
item.amount=100.00

That'll sort it out!
