Multiple MouseListeners? HELP

Hey there.
At the moment, i’m working on this site were the mainsite loads an external .swf holding a
dynamic newsbox with a mouseListener on it…like thus:

mouseListener=new Object();
mouseListener.onMouseWheel=function(delta){
scroller23.scroll-=delta;
}
Mouse.addListener(mouseListener);

My problem is, that the main .swf has got a dynamic tourlist (it’s for a band), also with a
mouseListener on it. My problem is, that whatever i call the mouselistener, it scrolls both dynamic textboxes. Is it not possible to have two seperate mouselisteners in the same movie?
And if possible, any good ideas on how to do it?

Hope someone can help me.
