Don't know how to finish challenge

I do not understand the instruction on the question, why doesn't my last line work?

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: "item")
item.amount = 100.0

var taxes = item.calculateTaxes(percentage: 7.5)

Bruno,

You got this bro, drop the "percentage"

like this: 

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)
