Multiple CS0128 "local variable is already defined' Error's. Please Help!

Getting these two error messages. Please Help!

Game.cs(17,17): error CS0128: A local variable named point' is already defined in this scope Game.cs(18,16): error CS0128: A local variable namedisOnMap' is already defined in this scope 

using System;

namespace TreehouseDefense.exe

{
    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);
          isOnMap = map.OnMap(point);
          Console.WriteLine(isOnMap);

        }
    }
}

MOD: I just fixed the code formatting so it looks better here - these should be back ticks (which are usually found above the tab key). Thanks!

Is it possible that the code shown here is different from what created the errors? For example, if the lines in question had declarations instead of the simple assignments as shown, that would cause those particular errors.

If that's not it, please provide a snapshot of the workspace to allow analysis and a more specific answer.
