init help

I am pretty sure I did this right but it says its wrong. Can anybody help me?

structs.swift 
struct RGBColor {
    let red: Double
    let green: Double
    let blue: Double
    let alpha: Double

    let description: String

    // Add your code below

    init(red: Double, green: Double, blue: Double, alpha: Double){
    self.red = red
    self.green = green
    self.blue = blue
    self.alpha = alpha
    self.description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)."
    }
}

let description = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)

Your code is good but you need to use self. rather than just red etc.. Here is the code that worked for me:

struct RGBColor {
    let red: Double
    let green: Double
    let blue: Double
    let alpha: Double

    let description: String

    // Add your code below
    init(red: Double, green: Double, blue: Double, alpha: Double) {
        self.red = red
        self.green = green
        self.blue = blue
        self.alpha = alpha
        self.description = "red: \(self.red), green: \(self.green), blue: \(self.blue), alpha: \(self.alpha)"
    }
}

I had a similar problem except on the Swift 3.0 version of the course. :P
