I am encountering an interesting error that someone hopefully can shed some light on.

I have an object that i want to remove from a Sprite once the y value reaches 0.

i made a Sprite and put one thing in it.

```php
var container:Sprite = new Sprite();
addChild(container);
var lB:Barrier = new Barrier();
container.addChild(lB);

```

I also added a mouse\_over listener and a enter\_frame listener.

now i have a different function that goes with the two listeners.  
in both of them i have a line for removing the lB clip.

```php
container.removeChild(DisplayObject(evt.target));

```

the line works just fine in the mouse\_over function.  
when the enter\_frame kicks in tho the clip gets removed also but then i get an error  
“The supplied DisplayObject must be a child of the caller” and the FPS go to about 1 lol

if anyone has any idea let me know …tnx all:beam::beam:
