I'm not really sure what's wrong with my function here. Buttons code challenge swift

I'd like a little help figuring out what's wrong with my method.

Button.swift 
class Button {
  var width: Double
  var height: Double

  init(width:Double, height:Double){
    self.width = width
    self.height = height
  }

 func incrementBy(points: Double) -> Double {
    return height * (points*width + 1)
 }
}

Hi Bradley,

The question wants points added to the height and width properties, but is not necessarily looking for a return value.

Example solution:

class Button {
  var width: Double
  var height: Double

  init(width:Double, height:Double){
    self.width = width
    self.height = height
  }

 func incrementBy(points: Double) {
    height += points
    width += points
 }
}

Hope this helps!
