Deselecting previous button on nav click

Hi All,

I wasn’t really sure how to title this one, but my issue is, I have a navigation with three buttons. When one button is clicked, it turns a certain color. When the next one is clicked, that one turns a different color, and the previous one turns back to it’s original color. So far when I click, the buttons turns colors, and then when i click on the other, the previous one doesn’t turn back. Can someone help me out with this one. Here is my code so far:


function navClick (e:MouseEvent) {
	
	var mc = e.currentTarget;	
	
	switch (mc.name) {
		
		case "link_num1":
		projectClick();
		TweenLite.to(mc.nav_color, .3, {tint:0xCCCCCC})
		break;
		
		case "link_num2":
		whoWeAreClick();
		TweenLite.to(mc.nav_color, .3, {tint:0xffffff})
		break;
		
		case "link_num3":
		commClick();
		TweenLite.to(mc.nav_color, .3, {tint:0xFF00000})
		break;
		
		default:
		TweenLite.to(mc.nav_color, .3, {tint:0x1A1A1A})
		
	}
	
}
