Thank you guys!
Thank you guys for opinions and idea.
Eric, I will read through again and study what you suggested.
It seems I need to take some time to comprehend your idea... (as English is not my first language, this whole learning process has been taking me double time!!)
I will come back again when I hit a wall and need your help again.
CraigR, I will try your suggestion and see if I can work it out.
(makes me feel so nice just to hear that I'm on right track when I had no clue where I was...!)
Again, thank you, and have a nice weekend.
