Image Pan _ Rubber band effect

Question

I am trying to make the black square do the rubber band
effect while the image pans left to right with mouse movement
Each code works seperatly but when i put them together they
do not work
here is layer 1 the code for the image pan
this.onMouseMove = function() {
constrainedMove(bg_mc, 4, 1);
function constrainedMove(target:MovieClip, speed:Number,
dir:Number) {
var mousePercent:Number = _xmouse/Stage.width;
var mSpeed:Number;
if (dir == 1) {
mSpeed = 1-mousePercent;
} else { mSpeed = mousePercent;
target.destX =
Math.round(-((target._width-Stage.width)*mSpeed));
target.onEnterFrame = function() {
if (target._x == target.destX) {
delete target.onEnterFrame;
} else if (target._x>target.destX) {
target._x -=
Math.ceil((target._x-target.destX)*(speed/100));
} else if (target._x<target.destX) {
target._x +=
Math.ceil((target.destX-target._x)*(speed/100));
here is the code for the movieclip on layer 2
MovieClip.prototype.move = function (centerx, centery,
inertia, k) { x = -this._x+centerx;y = -this._y+centery;xp =
xp*inertia+x*k;yp = yp*inertia+y*k;_x += xp;_y += yp;};
now the code for the actual squarebox
onClipEvent (enterFrame) {
this.move(x=247.5, y=300, 0.80, 0.1);
What am i doing wrong????
