Not sure what i'm doing wrong

Should i be putting anything after the purple arrow if the code isnt mean to be returning anything?

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

    init (description: String) {
        self.description = description
    }

    func calculateTaxes (percentage: Double) -> String {


}

Hey Becky Hayes,

No. You do not specify a return type if your function is not returning anything. If you don't specify a return type, a return of Void is implied. There are 3 ways to write a void return type:

// Function Returns Void - Method 1
func calculateTaxes(percentage: Double) {

}

// Function Returns Void - Method 2
func calculateTaxes(percentage: Double) -> () {

}

// Function Returns Void - Method 3
func calculateTaxes(percentage: Double) -> Void {

}

Good Luck
