@mbs, your initial request was relatively simple, and was answered.
Now your requests are for more advanced specific to your need/request.
As this forum is meant for people to get "help" (not a coding service), you will find that you will get the best response when you have put some effort in yourself.
As a "NEW" member of the forum, have you done your homework yet?
Like most things, you will learn more if you try it yourself first. So, show us YOUR code, or code that you are using (with reference to original coder), how you have modified it, and where it is not giving you what you are looking for. Then you might get some more specific help.
