Button problem

Hi, I am trying to make a website. It is almost done, but I am having some trouble. The way each paeg works is that when you click a link, it loads a new movie–the preloader. The preloader then, in turn another movie into a movieclip. My problem is as follows:

The movie successfully loads, but does not work correctly. On other pages I have had problems scrolling, but simply switching it to _parent instead or _root has done the trick. Unfortunately this will not work with this page. I am not using a custom sroll button, but rather I am using a scrollpane with an embedded media clip. The embedded clip has all the song titles. When you click on any lyrics title, it is supposed to go to the next frame, unfortunately I cannot get this to work. To see what im talking about, the website is
www.quintusmusic.com/jamar2.htm (then click on the lyrics link)

The code inside the movie clip that is inside the scroll pane is as follows. For each button, once clicked, it says _root.gotoAndStop(2). Now this worked before I added the preloaders so I assume it is a level problem. I have tried _parent and _global and have had no luck with either one. Any suggestions?
