You prob just need to store the new slidePos.
<a href="javascript://" onclick="increment()">scroll
right</a>
var slidePos = 0
function increment(){
slidePos = slidePos + .1;
slider2.setValue(slidePos);
}
var slider2 = new Control.Slider('handle2', 'track2', {
onSlide: function(v) { scrollHorizontal(v, $('scrollable1'),
slider2); },
onChange: function(v) { scrollHorizontal(v, $('scrollable1'),
slider2);slidePos=v }
});
im working on this issue now, let me know if that doesn't work
