Hi Jordan. I marked down your added code so it appears properly. To find out how to do that when you want to add some additional code you can check this post How to post code in the forums. Additionally, there is no question so it is hard for us to know what you need help with. Try adding more details on what you need help at.

Ps. Both codes are identical though.

Hey Jordan, if I remember well you should not return any value at this time of the task, it will tell you what to return in the next part

Hi. All you have to do is 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: "Savings") item.amount = 100 var taxes = item.calculateTaxes(7.5)
