Code challenge error

namespace Treehouse.CodeChallenges { class Polygon { public readonly int NumSides;

    public Polygon(int numSides)

        NumSides = numSides;
    }

 class Square : Polygon
 {

   public readonly int SideLength;

     public Square(int sideLength)
     {

       SideLength = sideLength;

   }   
 }

} }

:point_right: Your constructor is missing the explicit base call.

The challenge instructions include: "Use base to initialize NumSides to 4.". Adding that to your constructor would look like this:

     public Square(int sideLength) : base(4)
