This code is not working properly. If you could please finish the whole game for me. It should be as easy as using the mouse to move counters at the top of the connect 4 board and then it drops down and two players play against each other. The board and counters should have some concept of the becker robots in it. I know the explanation of how to do it but if someone could please type out the code to finish this game. Please Help
