challenge task 3 of 3 for what is inheritance

Question

It keeps telling me that I am failing this because "RoundButton" is not working. How do I get it to pass?
```Button.swift
class Button {
  var width: Double
  var height: Double
  init(width:Double, height:Double){
    self.width = width
    self.height = height
  }
  class RoundButton: Button {
  var cornerRadius = 5.0
  }
}
var rounded = RoundButton(width: 10.0, height: 20.0)
```

Hi Jeffrey,
You are very close.  Just move the RoundButton class outside of the Button class.  
If you try your code in the playground, you will instantly be alerted to the mistake.
I find that trying out code challenges in the Playground is the fastest way to learn.
```swift
class Button {
    var width: Double
    var height: Double
init(width:Double, height:Double){
    self.width = width
    self.height = height
}
}
class RoundButton: Button { // move outside of Button class
    var cornerRadius = 5.0
}
var rounded = RoundButton(width: 10.0, height: 20.0)
```
I hope that helps,
Mike
