Buttons scripting help

Question

Hi,
I have been working on making a menu for list items but have not had much luck scripting (due to lack of knowledge and time restrictions any help would be great)!
The file below has an amimated menu.
if you click on Artificial Intelligence on frame 60,  it jumps to frame 61 (a specific section for that list item).
How do I make the Artificial Intelligence button on frame 61 jump back to frame 60?
I dont know where to add the action script for the function please can you help.
I need to add a similar script to all 9 list items, do they go on one actionscript file? if so what location?

Thanks in advance.

Answer 1

Yes, that makes sense, I tried it and all seems to be working fine, now I have to try and impliment this to 9 list items and have an idea that each action script ought to go within the frame itself.
Some one also suggested that I use this script that I have not tried yet but looks neat just incase anyone is interested:
import flash.events.MouseEvent;
var atHome:Boolean = true;
AIbutton.addEventListener(MouseEvent.CLICK, AItoggle);
function AItoggle(e:MouseEvent):void{
    if (atHome == true){
        gotoAndStop(frame lable/frame number);
        atHome = false;
    } else {
        gotoAndStop("home"/frame lable);
        atHome = true;
I will try this next to see what ahppens, it will save me from creating a lot of duplicate list items (one for home page, one for specific frame).
Thank you for the help, I was stuck!
