Rather than try to display all the options on the screen, why not display one at a time and use the scroll keys to select. That way you can have any number of options without having to faff around scrolling blocks. Keep it simple - this is the way most mobile phones operate their menu systems. If you think carefully about you menu system, you can create a simple table driven structure that will allow you to add extra menus without having to write code. As I said, keep it simple - your customers will love you for it and it will make your job easier!
