what am i doing wrong??? can someone please help me?

Then 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.

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))
    }
// <--  put it on this line

    var item = Expense(description: "Car")
   item.Expense = 100

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

}  // <--- move this to the point indicated above

You need to take the var item = Expense etc. outside of the Struct definition. So, move the closing curly brace above those lines.

I've put some comments in your code above to illustrate the point.
