How to close 2 swf using unloadMovie function?

programming flash
1

So far I’m woking for 3 swf’s, one is the holder which load the swf’s, I named
table.swf, box.swf and fruit.swf
table.swf is my holder and has a button of this code:

on(release){
	loadMovie("box.swf",2);
}

to load the box.swf, then the box.swf has its own button also to appear the fruits inside the box with this code:

on(release){
	loadMovie("fruits.swf",3);
}

also I put the closed button to box.swf with this code

on(release){
   unloadMovie(2 && 3);
}

But it didn’t work when i press the “X” button of box.swf, the box and the fruits did’nt close.
any help would be great!
