Creating an over area with x & y mouse positions

programming flash

I’m trying to create an area that causes a menu to fade in, similar to the toolbar in Mac OSX. So when the mouse nears that area the menu pops up, I’ve been trying it with some code, not sure if I’m heading in the right direction. Any help as usual greatly appreciated.

onClipEvent (enterFrame) {
_root.top = 8;
_root.bottom = 104;
_root.left = 367;
_root.right = 744;
if (_root._xmouse > _root.right) {
if (_root._ymouse < _root.bottom){
this.gotoAndStop(“in”);
} else {
this.gotoAndStop(1);
}
}
if (_root._xmouse > _root.right) {
if (_root._ymouse > _root.top){
this.gotoAndStop(“in”);
} else {
this.gotoAndStop(1);
}
