Slider HELP Please

[banehavoc]

I am trying to change the vertical chat slider and button in a custom UI I am building. My problem is this.
Can I use the same graphic for both the slider and button as my horizontal slider for the vertical slider?

The problem is not with the channel but the button itself I understand how to make the channel the button sits on/in, but the button is made of 3 pieces. How can I make the button a static button that is draggable and doesnt scroll in the channel , I don't want the button to stretch but to stay the same size at all times no matter where it is on the slider.

I hope I didnt make this sound too hard seems very simple to me because the horizontal slider can do it. It seems that I should be able to do the same thing with the vertical chat slider ?

I am good at graphics but not sure how to make this work any help would be appreciated.
