Scrolling Menu... arrgghh!

[squidlips]

I have a menu bar that is 1906 pixels wide. It is on the main timeline of a movie that is 550 pixels wide. I implimented an old easing actionscripy that I had but I can't get it to work.

Here is the code I am currently using (embedded in the movieclip)...

onClipEvent (enterFrame){
   difX=this._x-_root._xmouse;
   difXE=difX/5;
   difXM=this._x-difXE;
   tellTarget(thi, _x, difXM);
}

I experimented with a few other things, because the main problem was the movie wasnt moving far enough each way, so I tried...

onClipEvent (enterFrame){
   mousepower=_root._xmouse*3
   difX=this._x-mousepower;
   difXE=difX/5;
   difXM=this._x-difXE;
   tellTarget(thi, _x, difXM);
}

... and other things similar but none of them worked effectively.

What am I doing wrong?
