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 {


}

Hi Becky! I think you are going in the right direction! And I would like to help you out here, and I think the question says that the function "calculateTaxes" should return nothig. So the -> String is not needed here. :) and you might be missing one curly bracket.

so it should look like this:

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

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

    func calculateTaxes (percentage: Double) { 
   }

}
