Random move with dragable in bouded area

Question

respected sir i m doing hard work since 6 months,u r god 4 me
,if u help me..plzzz
My prb : i want make a object (random movement with dragable
in bounded area like a farm hause.
----------------------Bounded movement
onEnterFrame = function() {
with (_root.yash){
x1 = _x;
y1 = _y;}
var shapeFlag = true;
if (_root.dragArea.hitTest(x1,y1,true)) {
if (dragArea._x < yash._x-20){
yash._x = dragArea._x+(yash._x-100)
} else
if (dragArea._x > yash._x+20){
yash._x = dragArea._x-(yash._x+100)
} else
if (dragArea._y < yash._y+20){
yash._y = dragArea._y+(yash._y-100)
}else
if (dragArea._y > yash._y+20){
yash._y = dragArea._y-(yash._y+100)
----------------random movement and dragable
onClipEvent (load) {
//data you may want to change
width = 550;
height = 400;
speed = Math.round(Math.random()*2)+1;
//initial positions
x = Math.random()*width;
y = Math.random()*height;
this._x = x;
this._y = y;
x_new = Math.random()*width;
y_new = Math.random()*height;
onClipEvent (enterFrame) {
//x movement
if (x_new>this._x) {
sign_x = 1;
} else {
sign_x = -1;
dx = Math.abs(x_new-this._x);
if ((dx>speed) || (dx <-speed)) {
this._x += sign_x*speed;
} else {
x_new = Math.random()*width;
//y movement
if (y_new>this._y) {
sign_y = 1;
} else {
sign_y = -1;
dy = Math.abs(y_new-this._y);
if ((dy>speed) || (dy <-speed)) {
this._y += sign_y*speed;
} else {
y_new = Math.random()*height;
onClipEvent(enterFrame){
if(drag){
_x = _parent._xmouse;
_y= _parent._ymouse;

The else part modified:
else
{ // not a corner point: keep handles in same relative position to their shifted anchor
    var aShift = Math.random()*cShift;
    var bShift = Math.random()*cShift;
    thisPoint.anchor = [va  + aShift, vb + bShift];
    thisPoint.leftDirection = [la + aShift, lb + bShift];
    thisPoint.rightDirection = [ra + aShift, rb + bShift];
