Rollover, hitTest question

1

I’m making a menu with rollovers.
So when I go over a coloured part, it’s getting larger and soms subitems appear. Those subitems must be clickable, but when I use an onRelease, my coloured part is getting smaller again.

this is my code so far:

for(var i=0;i<aantalSubItems;i++)
	{		
		subItem_mc = blokje_mc.createEmptyMovieClip("subItemMC"+i,blokje_mc.getNextHighestDepth());
		subItem_mc.createTekstVeld(subItems*.attributes["text"],"tekst",stijl);
		subItem_mc._y = i*12+15;
		subItem_mc.onMouseMove=function()
		{
			if(this.hitTest(myObject.$root._xmouse,myObject.$root._ymouse,false))
			{
				trace(this);
				
			}
		}
			
	}

I’m first using a rollover and then a hitTest, should I switch??
Or does anybody have a solution??
