iOS Swift Enums and Structs Structs and their Methods Struct Methods

Can someone help me with this excercise?

Trying this Struct and their methods excercise and i can't seem to quite get it. This is what i have so far

struct Expense { var description: String var amount: Double = 0.0

init (description: String , amount: Double) {
    self.description = description
    self.amount = amount
}

func calculateTaxes(percentage: Double) -> Double
{
    return self.amount*(percentage/100)
}

}

var item = Expense(description: "Hello", amount: 100)

I run it but it still gives me an error, Does anyone know why?

struct.swift
struct Expense {
    var description: String
    var amount: Double = 0.0

    init (description: String , amount: Double) {
        self.description = description
        self.amount = amount
    }

    func calculateTaxes(percentage: Double) -> Double
    {
        return self.amount*(percentage/100)
    }

}

var item = Expense(description: "Hello", amount: 100)

var item = Expense(description: "Hello", amount: 100), Expense constructor takes only one argument, and you passed in 2.

var item = Expense(description: "Hello")
item.amount = 100

Also, do not modify the init method by adding another parameter amount, because that's not what the challenge is asking for.

Enter any description you like). On the next line assign the amount property a value of 100.
