Having trouble with the Polygon / Square challenge

I've tried coding the answer as much as possible but it seems the code does not work. Can you please let me know what I have done wrong?

Polygon.cs 
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 numSides) : base(4)
        {

        }

    }    


}

When I try this in the challenge it gives a clue: "Bummer: Does your Square constructor take a single parameter named sideLength?" But the parameter here is named "numSides" instead.

Also, you'll need to initialize the SideLength field (capital "S") with that value in the body of the constructor, in the same way that "Polygon" does with "NumSides".
