Kirupa's Slider Bar: Changing values?

Hi all,

I have a project that I’m trying to incorporate Kirupa’s slider bar into. I can’t seem to figure out how to control the value increments as the slider is dragged. I need it to probably go in increments of 1000. Can anyone help me out with this one?

Here’s the actionScript:

this.ratio=0 ;
dragger.onPress=function(){
this.startDrag(true,0,0,line._width,0);
this.onEnterFrame=function(){
ratio=Math.round(this._x) ;
}
}
dragger.onRelease=dragger.onreleaseOutside=stopDrag;

Thanks!
