Need help with this code challenge

I just can't figure out what's wrong here. I did define 'Square' as 'Polygon's' child

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

        public Polygon(int numSides = 4)
        {
            NumSides = numSides;
        }
    }
    class Square : Point
    {
    public readonly int SideLength;
    public Square (int sideLength) : base(numSides)
    }
}

There should be "Polygon" instead of "Point", but it doesn't fix the problem.

Initialize SideLength in the Square constructor:

SideLength = sideLength;

Initialize NumSides for Polygon using the base keyword:

public Square(int sideLength) : base(4)

Remove the default initialization of numSides in the constructor for Polygon (i.e., change "numSides = 4" to "numSides").

I hope this helps. :)
