Hello, please see the file attached. I have 1200x900 px stage that includes  
5 (400x300 px) Mcs and 1 (800\*600 px) MC. All of these are external SWFs. the think I want it everytime I open the main SWF I want number 6 stay at the same place while other 5 will change places in a random manner.  
How to achieve that ? Thanks so much.

I use this:

boxes = Array();  
for(i=0; i\<5; i++) {  
newMc = Math.floor(Math.random()\*4);  
boxes.push(newMc);  
loadMovie(“mc”+i+".swf", “holder”+newMc);  
}  
loadMovie(“mc6.swf”, “holder6”);

now I know the thing I need to do is, if the random generated newMC exists in boxes array it have to regenerate another one that doesnt in the boxes. But I cant find a command or sloution to do that.
