The question asks me to assign the amount variable to 100 on the line beneath the item variable, why does it not take?

The question asks me to assign the amount variable to 100 on the line beneath the item variable, why does var amount = 100 not take?

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: "Taxes")
var amount = 100

    // add the calculateTaxes method here
    // it should accept only one parameter named 'percentage' of type Double

}

It should be 

item amount = 100

and not 

var amount = 100

Hope that helps!

You need to include the last two line outside the brackets...Here's the full code: 

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: "description")
item.amount = 100

Hope this works
