The name 'width' does not exist in the current context.

I thought my codes are as same as the ones written in the video, but the compiler said that "Map.cs(16,40): error CS0103: The name 'width' does not exist in the current context." How could I fix this error?

Game.cs

using System; namespace TreehouseDefense { class Game { public static void Main() { Map map = new Map(8, 5);

      Point point = new Point(4, 2);
      bool isOnMap = map.OnMap(point);
      Console.WriteLine(isOnMap);

      point = new Point(8, 5); //zero base counting
      Console.WriteLine(isOnMap);
    }
}

}

Map.cs namespace TreehouseDefense { class Map { public readonly int Width; public readonly int Height; 

public Map(int width, int height)
{
  Width = width; 
  Height = height; 
}

public bool OnMap(Point point)
{
  return point.X >= 0 && point.X < width &&
         point.Y >= 0 && point.Y < height; 
}

} }

Thanks a lot.

:point_right: You probably need to spell "Width" with a capital "W".

Remember that C# is case-sensitive, and the read-only instance variables of the Map object are Width and Height, both spelled with a capital first letter.
