hi there

please can somone help with this little problem, I have a demo file that I am trying to created a constraint to a rectangle. I have the startDrag working and I am trying to constrain a square to the movie size of 600x400.

I have been searching online help files but I can not for the life of me get it to work, would someone beable to put me out of my misery. I have attached the demo file I am working with but I will also post my script here for thoughs who prefer that…going crazy, can any help, does it have to be this difficult…aarrrghh!!

this is what I thought I could simply add

```auto
("animation", false, 0, 0, 300, 300);

```

but know joy…anyone help 😕???

my code:

```auto
 
////Button Listeners/////////////
// BtnNav listeners
btnNav.addEventListener(MouseEvent.ROLL_OVER, btnNavOver);
btnNav.addEventListener(MouseEvent.ROLL_OUT, btnNavOut);
btnNav.addEventListener(MouseEvent.CLICK, btnNavDown);
// change: made the graphic "red shape" a movieClip and made redShape and closeBtn a movieClip
// added this listener to that button...
animation.redShape.closeBtn.addEventListener(MouseEvent.MOUSE_UP,closeUp);
////for the click and drag
animation.addEventListener(MouseEvent.MOUSE_DOWN,dragStart);
animation.addEventListener(MouseEvent.MOUSE_UP,dragStop);
 
 
///////button 1 function ///////////
// BtnNav Over function
function btnNavOver(event:MouseEvent):void {
btnNav.gotoAndPlay("over"); // go into btn1 movieclip and play the over frame label
}
// BtnNav Out function
function btnNavOut(event:MouseEvent):void {
btnNav.gotoAndPlay("out"); // go into btn1 movieclip and play the out frame label
//animation.stopDrag();
}
// BtnNav Down function
function btnNavDown(event:MouseEvent):void {
 // change: tell the movieClip animation to play...
 animation.play();
 
//this.gotoAndPlay("animation"); 
// play any frame label in any movieclip
}
// change: added this function for the close button to have it play the animation clip...
function closeUp(event:MouseEvent):void {
 animation.play();
}
/////for the click and drag////
function dragStart(event:MouseEvent):void {
    event.currentTarget.startDrag();
 //("animation", false, 0, 0, 300, 300);
 
}
function dragStop(event:MouseEvent):void {
    stopDrag();
}
 

```
