Excel VBA Button Help

[rdroy1754]

Hello. I just recently began to learn about writing code within excel VBA. I have a project for school where I must create a board game and I choose to use excel. I wanted to make a VBA version of connect 4 but was only able to make a mixture of connect 4 and tic tac toe. I am trying to add buttons above the 7 columns of boxes that will drop a chip into an empty column below. Right now, I can click any box and place a chip which is not true to connect 4 seeing that the chips must stack on top of each other. Can any one please help me with the code for this? I've attached a copy.
