Hover function not working when loaded into movie clip holder

Hi

AS 2 question:

I am having issues with a hover funtion in a loaded swf file.

  1. Hover file swf works on its own.
  2. Parent file swf loads hover swf
    [COLOR=darkred]3. Hover funtion no longer works in parent swf[/COLOR]
    [COLOR=#8b0000][/COLOR]
    [COLOR=black]Here is the code for the hover swf[/COLOR]
var hoverMC:MovieClip;
var myInt:Number;
var d:Number = _level0.getNextHighestDepth(); // set this once so we only have one hover at a time
function moveHover(){
 hoverMC._y = _level0._ymouse;
 hoverMC._x = _level0._xmouse;
 if(!hoverMC._visible) hoverMC._visible = true
}
function showHover(mc){
 hoverMC = _level0.attachMovie(mc, "hoverMC", d);
 hoverMC._visible = false;
 myInt = setInterval(moveHover, 50);
}
function hideHover(){
 hoverMC.removeMovieClip();
 clearInterval(myInt);
}

btn1.onRollOver = function(){
 // make sure you set the linkage idendifier
 // of the MC you want to attach in the propertiers panel
 _level0.showHover("hoverMC1")
}
btn1.onRollOut = btn1.onDragOut = btn1.onReleaseOutside = function(){
 // hide whatever hover MC is available
 _level0.hideHover();
}

Code for parent swf loading the hover swf

_root.currMovie = "section2";
container.loadMovie(_root.currMovie+".swf");

Any help or points to reference material would be appricated.

Thanks
