Does your Square include a parameter named SideLength?

Hi. This is the message I got after running my code, which I understand I can attach to this post.

I can't see where I'm going wrong given the solution in this thread:

https://teamtreehouse.com/community/it-is-very-hard-for-my-figure-out-the-problems-can-someone-help-me

I'd appreciate any help please.

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(4)
        {
            SideLength = sidelength;
        }
    }
}

Your code seems fine, but based on the error message the challenge is apparently expecting the parameter name to be "sideLength" (with capital "L"), but the code here uses "sidelength" (with lower-case "l") instead.

You might want to report this as a bug to Support, since the instructions didn't mention using a specific parameter name.

Hi Steven. You're right; I should have used an upper-case "L" for SideLength when declaring the readonly field and again for the parameter name.

Thank you!
