What is wrong with the code below that I'm getting the error message below: Bummer! Did you initialize

Why am I getting the error message: Bummer! Did you initialize the field 'numSides' to 4 in the base constructor?

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

    public Polygon(int numSides)
    {
        numSides = 4;
        NumSides = numSides;

    }
}

class Square : Polygon
{
    public readonly int SideLength;

    public Square(int sideLength) : base(numSides)
    {
        SideLength = sideLength;
    }
}

}

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

        public Polygon(int numSides)
        {
            NumSides = numSides;
        }
    }
}

:point_right: The constructor for Square can use "base(4)" to initialize numSides.

The code added should only be for the new class Square. You should not change the code provided by the challenge for Polygon.
