Va esta respuesta, a ver si sirve.

Código:

// function for the Next button
function nextMenuItem(eventObj:Object) {
	slideShow_mc.gotoAndPlay("slide"+(currImage));
	if ((currImage+1)>=totalImages) {
		currImage = 0;
	} else {
		currImage++;
	}
	menu_mc.title_txt.text = this._parent["image"+currImage+"title"];
	menu_mc.description_txt.text = this._parent["image"+currImage+"desc"];
}
// function for the Back button
function backMenuItem(eventObj:Object) {
	slideShow_mc.gotoAndPlay("slide"+(currImage));
	if ((currImage-1)<=0) {
		currImage = totalImages;
	} else {
		currImage--;
	}
	menu_mc.title_txt.text = this._parent["image"+currImage+"title"];
	menu_mc.description_txt.text = this._parent["image"+currImage+"desc"];
}
// add the event listener for the Next button
next_btn.addEventListener("click", nextMenuItem);
back_btn.addEventListener("click", backMenuItem);
