What am I doing wrong?

I can't figure out what's wrong with my code. It says there's an error but doesn't specify what it is.

Hey. So next time try showing your current code - it makes it easier to help - without giving you the answer completly :-)

But here is what the answer should look like:

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:"Hotel")
item.amount = 100.00

var taxes = item.calculateTaxes(7.5)
