custom initializer task - what am I doing wrong?!

the more I look at the instructions to this task the more confused I get. I feel like I wrote the right code, so I cannot for the life of me understand why it keeps saying "Bummer. Don't use the swift memberwise initializer. Add your own custom initializer as specified in the description."

I assume the problem has something to do with how and where I assign the value to "description", but I am honestly lost. Please help. I cannot move on in my life before I have solved this...

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

}

You refer to the "alpha value" in the struct's "init" as "aplha", simply change the "aplha" to "alpha" and the code will work :)
