If you would like programming help at this level, you need to provide the code you are working with, otherwise it is too time consuming to figure out exactly what you are doing and all anyone could provide is best guesses. Although, I think I understand where you are going with this code, spending time answering all your questions benefits very few members on the board -- since there are no examples.

Normally, I would just not reply to the question, but I wanted you to understand why you might not receive any replies. If you care to re post with your uncompleted code, I will take another look at what you are asking.
