One object following the mouse AND a path

Alright, I’m trying to design my very first flash website, to date I’ve been using a photoshop/imageready and HTML combo and I need something new. So, I bought Flash MX 2004, and thus my question regards AS 2.

My problem is, I want an object to follow a path (like a motion guide) but I want its X position to be determined by the mouses X position. This is to be this way so that no matter where your cursor is (it will be hidden) the object following the path and your mouses X position will be the same. I tried to just make a motion guide and then use the following AS but it did not work.

onClipEvent (enterFrame) {
myRadians = Math.atan2(_root._ymouse-this._y, _root._xmouse-this._x);
myDegrees = Math.round((myRadians*180/Math.PI));
_root.yChange = Math.round(_root._ymouse-this._y);
_root.xChange = Math.round(_root._xmouse-this._x);
_root.xMove = Math.round(_root.xChange/10);
this._x += _root.xMove;
this._rotation = myDegrees+90
Mouse.hide();
}

That is just modified AS from a tutorial I read. It makes the object follow my mouses X position and rotate according to specific degrees (makes it more interesting). The problem is that I need the objects Y value to be a set value along a curved line. And I have no idea how to do this. I was reading something about the path follower class but thats way above my head. So is there an easier way to do this? Or could someone explain how I would go about using the path follower class in such a manner? Thank you, imagiu(s)!
