Maybe someone could, but you will first have to explain your code to us. In other words: At least provide your code with sufficient comments. You cannot expect the forum members to spend their time trying to reverse engineer your code, in order to be able to correct the errors...

Furthermore, I think you should try to write it and try to make it work. I cannot (and will no) do your work. I've got my own...

If you have given it a try, and it does not work, then come back and ask for help...
