Expanding link menu... slight problems

programming flash

Any idea why this might not be working? this is my first attempt at one of those dynamic menus… but for some reason its a little funky. I can’t get the links to return to their original locations… any suggestions?
site so far

var aboutEnd = 230;
var aboutStart = -5;
var link2End = 170;
var link2Start = -135;
function btnAction(linkName, linkEnd){
	if (linkName._y != linkEnd){
		linkName._y = Math.ceil((linkName._y - linkEnd/5)/1.3);
	}
	if(circle._y != linkEnd){
		circle._y = Math.ceil((circle._y - linkEnd/5)/1.3);
	}
}
function btnReturn(linkN, linkS){
	if (linkN._y != linkStart){
		linkN._y = Math.ceil((linkN._y - linkS/5)/1.3);
	}
}

link1.onRelease = function(){
		gotoAndPlay(2);
		this.onEnterFrame = function(){
		btnAction(link1, aboutEnd);
		btnReturn(link2, link2Start);
	}
}
