Custom Init to Create a Property Description from the RGBA Values

The challenge is for me to create a description from the given values of RGBA

The description is suppose to look like this. "red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0"

I am trying to figure out why I am getting this error:

Bummer! The value of description does not match with the directions specified.

I am unsure if the program wants me to give it values of: R-86.0, G-191.0, B-131.0, A-1.0 values or if my description is off by a slight error. For instance a space or , being out of place.

It could also be I am not following directions the right way.

I have tried to multiple ways and yet I still seem to get the same error.

Thank you in Advanced for any help.

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
      description = "red:\(red),green:\(green),blue:\(blue),alpha:\(alpha)"
    }
}
