Importing scrollbar actions

Question

My problem is I'm trying to play a function contained in an as. file. It's not the main function in the class file. When I downloaded the sample, the as. file was in the same file as the fla, and the only actionscript in the fla file was
sb.init(txt_mc, "easeOutBack",2,true,2);
I tried saving it in the same file just as the sample but when i tested it I get an output error stating init is not a function (I'm guessing because it's not in the first frame like in the sample). so i just moved the as file with to the rest of my class files, and i tried this
import com.mysite.mouse.Scrollbar;
var Scroll:init = new init();
sb.Scroll(txt_mc, "easeOutBack",2,true,2);
I'm not too sure of myself when it comes to importing class files, but here's how the as. file is set up
Package....
import statements...
public function Scrollbar():void {
scroller.addEventListener(MouseEvent.MOUSE_DOWN, dragScroll);
stage.addEventListener(MouseEvent.MOUSE_UP, stopScroll);
stage.addEventListener(MouseEvent.MOUSE_WHEEL,mouseWheelHandler);
public function init(t:MovieClip, tr:String,tt:Number,sa:Boolean,b:Number):void {
target = t;
trans = tr;
timing = tt;
isArrow = sa;
sBuffer = b;
etc.....

If Scrollbar is the name of the package, then I believe that is what you need to declare...
var Scroll:Scrollbar = new Scrollbar();
Scroll.init(txt_mc, "easeOutBack",2,true,2);
I am not well versed in class/package matters, so a grain of salt might help, but I am pretty sure your class, Scrollbar, is what you assign as a new instance, and then you utilize the class methods/properties thru the instance created.
