creating new buttons on different frame labels

can someone tell me if im doing something wrong or assigning the as to the wrong frame?

first off i have all my buttons on frame 2. im creating a real estate site and i have to have a couple links like HOME ABOUT BUYING SELLING CONTACT, the thing though is that in the BUYING and SELLING frames i want to add more sections and links but only on these 2 other parts of my site. when i code it and add new buttons to these sections though my movie plays over and over and over non stop. heres my coding...

FRAME 1 preloader

Frame 2 has a frame label of home and all the buttons on a diff layer, and AS3 on a different layer

Frame 3 has a frame label for about section

Frame 4 is my contact for example



so if i create a new button in the about frame label and just add the code to the working as3 code on frame 2 my movie just plays over and over and over again, and all i want it do do is act like the other buttons and go to a different frame label down in the time line. the only way i get it to work is if i have ALL my buttons on frame 2.






frame 1
my preloader

frame2

home_btn.addEventListener(MouseEvent.CLICK, onHome)
function onHome(event.MouseEvent):void
{
gotoAndStop("home");
}


about_btn.addEventListener(MouseEvent.CLICK, onAbout)
function onAbout(event.MouseEvent):void
{
gotoAndStop("about");
}

etc....

etc...

i enter my btn code just like this and the buttons on frame 2 work but any new buttons i try and creat and put into different frames othere then frame label "home" aka frame 2 wont work
