Compiler Error

Hi,

I have received the following compiler error; Polygon.cs(13,18): error CS1519: Unexpected symbol `public' in class, struct, or interface member declarationCompilation failed: 1 error(s), 0 warnings

I believe everything is fine. Is it?

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(4)

    {
        SideLength = sideLength;

    }

}

}

:point_right: it looks like you're defining the Square class inside the Polygon class.

The classes are both part of the same namespace, but should be at the same nesting level within it.
