On the second time I go back to the button, it doesnt work anymore?

Question

Hello,
Well im still busy making an animation and I got stuck.
The animation goes as following: I have 15 buttons active at this moment, I only programmed 1 so far. If I click on this 1 button (linkslinksboven_btn) it goes to a certain frame, in this case frame 181. In frame 181 I have 4 new buttons which 1 is programmed yet, if I click on this button (linkscirkellinks_btn) I made some lines go to a colour and a letter "M" is turning 10 times during 10 seconds. After those 10 seconds that little animation stops and I have to click on a button (onzichtbareknoplinkslinksboven_btn) that goes back to where my 15 buttons are active which should be at frame 180, so all 15 are able to get clicked again. So I click on the button, it shows my 15 buttons but when I click on the 1 I programmed and used earlier it does nothing?
Here's all the coding on my first keyframe:
//---Frame stop @ frame 180---\\
addEventListener(Event.ENTER_FRAME, onEnterFrame180);
function onEnterFrame180(e:Event):void {
     if (currentFrame == 180) stop();
//---Knop linksmidden_btn---\\
linksmidden_btn.addEventListener(MouseEvent.CLICK, linksmidden_btnClick);
function linksmidden_btnClick(event:MouseEvent):void{
    gotoAndPlay(180);
//---Knop linkslinksboven_btn---\\
linkslinksboven_btn.addEventListener(MouseEvent.CLICK, linkslinksboven_btnClick);
function linkslinksboven_btnClick(event:MouseEvent):void{
    gotoAndPlay(181);
//---Knop linksrechtsboven_btn---\\
linksrechtsboven_btn.addEventListener(MouseEvent.CLICK, linksrechtsboven_btnClick);
function linksrechtsboven_btnClick(event:MouseEvent):void{
    gotoAndPlay(182);
//---Knop linkslinksmidden_btn---\\
linkslinksmidden_btn.addEventListener(MouseEvent.CLICK, linkslinksmidden_btnClick);
function linkslinksmidden_btnClick(event:MouseEvent):void{
    gotoAndPlay(183);
//---Knop linksrechtsmidden_btn---\\
linksrechtsmidden_btn.addEventListener(MouseEvent.CLICK, linksrechtsmidden_btnClick);
function linksrechtsmidden_btnClick(event:MouseEvent):void{
    gotoAndPlay(184);
//---Knop linkslinksonderbovenkant_btn---\\
linkslinksonderbovenkant_btn.addEventListener(MouseEvent.CLICK, linkslinksonderbovenkant_btnClick);
function linkslinksonderbovenkant_btnClick(event:MouseEvent):void{
    gotoAndPlay(185);
//---Knop linkslinksonderonderkant_btn---\\
linkslinksonderonderkant_btn.addEventListener(MouseEvent.CLICK, linkslinksonderonderkant_btnClick);
function linkslinksonderonderkant_btnClick(event:MouseEvent):void{
    gotoAndPlay(186);
//---Knop linksrechtsonderonderkant_btn---\\
linksrechtsonderonderkant_btn.addEventListener(MouseEvent.CLICK, linksrechtsonderonderkant_btnClick);
function linksrechtsonderonderkant_btnClick(event:MouseEvent):void{
    gotoAndPlay(187);
//---Knop linksrechtsonderbovenkant_btn---\\
linksrechtsonderbovenkant_btn.addEventListener(MouseEvent.CLICK, linksrechtsonderbovenkant_btnClick);
function linksrechtsonderbovenkant_btnClick(event:MouseEvent):void{
    gotoAndPlay(188);
//---Knop rechtsonderkant_btn---\\
rechtsonderkant_btn.addEventListener(MouseEvent.CLICK, rechtsonderkant_btnClick);
function rechtsonderkant_btnClick(event:MouseEvent):void{
    gotoAndPlay(189);
//---Knop rechtsbovenkant_btn---\\
rechtsbovenkant_btn.addEventListener(MouseEvent.CLICK, rechtsbovenkant_btnClick);
function rechtsbovenkant_btnClick(event:MouseEvent):void{
    gotoAndPlay(190);
Here's the coding at the second keyframe wich is at frame 181:
stop();
//---Knop linkscirkellinks_btn---\\
linkscirkellinks_btn.addEventListener(MouseEvent.CLICK, linkscirkellinks_btnClick);
function linkscirkellinks_btnClick(event:MouseEvent):void{
    gotoAndPlay(182);
//---Knop linkscirkelboven_btn---\\
linkscirkelboven_btn.addEventListener(MouseEvent.CLICK, linkscirkelboven_btnClick);
function linkscirkelboven_btnClick(event:MouseEvent):void{
    gotoAndPlay(183);
//---Knop linkscirkelrechts_btn---\\
linkscirkelrechts_btn.addEventListener(MouseEvent.CLICK, linkscirkelrechts_btnClick);
function linkscirkelrechts_btnClick(event:MouseEvent):void{
    gotoAndPlay(184);
//---Knop linkscirkelonder_btn---\\
linkscirkelonder_btn.addEventListener(MouseEvent.CLICK, linkscirkelonder_btnClick);
function linkscirkelonder_btnClick(event:MouseEvent):void{
    gotoAndPlay(185);
And then finally on my last keyframe so far at frame 481:
stop();
//---Knop onzichtbareknoplinkslinksboven_btn---\\
onzichtbareknoplinkslinksboven_btn.addEventListener(MouseEvent.CLICK, onzichtbareknoplinkslinksboven_btnClick);
function onzichtbareknoplinkslinksboven_btnClick(event:MouseEvent):void{
    gotoAndPlay(180);
Does anyone know why I cannot click on the linkslinksboven_btn when I get to that frame for the second time?
Every help or even tips to make my step easyer are welcome! Im open to learn! =)

You probably need to have your buttons' code at frame 180 instead of any earlier frame.  If the 15 buttons end at frame 180, but the code for them is at frame 1, then when you move beyond frame 180 you essentially lose the buttons, and if you move back to frame 180, there is no code there to assign functionality to the buttons.
