Menu Slider? HELP

I am making a menu and wish to have a slider. I want the slider however to be an object that frames a letter. The slider tutorial shown at http://www.kirupa.com/developer/mx2004/menu_with_slider.htm
is close however the slider goes to the center of each button. How do I get the slider to move at a different scale and in a different location coresponding with that text instead of the center of each button that I run the mouse over???

If this is confusing let me know I will try to help!
