Add a method to the Expense struct that will calculate taxes based on a percentage passed to the method

I have no idea what I am doing wrong. Somebody please help me.

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

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

{
  func calculateTexas(percentage: Double) {
}
}

Something like: 

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

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

  func calculateTaxes(percentage: Double) {
  }
}

Check you Brackets. The close bracket for your init function is an open bracket vs. close.

I think you're pretty much there. Two things, though. One was mentioned by Kevin above; your braces aren't quite right.

Second, as just because the first part of the challenge requires nothing inside the method, is the spelling. You're calculating Taxes not Texas. ;-)

I think if you fix those two things, you'll get to the next stage. If not; just shout and we'll come and help.

What should the brackets be instead of what I have?

Change from { to } right above your function call.

In the first challenge the function does not return anything, so it should be:

func calculateTaxes(percentage: Double) () {
}

Hi Kevin,

I don't think the () are needed as omitting the return arrow and type is sufficient to show the function isn't returning anything.

I think. I'm no expert.
