Whats wrong?

Hi. I'm having problems understanding this question. I guess it's my poor english that is the issue. Can someone please look at my code and explain whats wrong?

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

    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)"

I think you have to put a colon behind "alpha".

Ah, thats so sloppy. Thanks a lot Moritz!
