Did you use the 'base' keyword after the Square constructor to call the Polygon constructor?

I cant seem to get past this error. It keeps asking: "Did you use the 'base' keyword after the Square constructor to call the Polygon constructor?" I did use the base keyword but I must be using it wrong. Any suggestions?

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 sideLength) base(NumSides)
        {
            SideLength = sideLength;
        }
    }
}

You are missing a : before base.

Instead of passing in NumSides, try passing in 4 to initialize NumSides to 4.
