Attaching movieclips

Why doesn’t this work? This code is in one of the movieclips on the stage inside onEnterFrame-handler.


    if(_root.printed==0)
    {
      
        for(i=0;i<_root.lives;i++)
        {    
        _root.attachMovie("lifex", "lives"+i, 30000+i);
        axa=24*i;
        yxy=200;
        setProperty ("lives"+i, _x,axa);
        setProperty ("lives"+i, _y,200);
        }        
    
    _root.printed=1;
    }

When I list the objects it says all the objects are there, but I only see one. What’s wrong?
