HELP: Preloader and Button AS3

Question

Hi guys!
I used to work on AS2 to make my animations, buttons and portfolios, but now I needed to use AS3 to make some forms interact with some PHP script.
TextInputs and Buttons on COMPONENTS are working and interacting normally with PHP. My PreLoader is working great too. But what should the easiest is not working: MY SIMPLE BUTTONS! It used to be so easy in AS1 and 2, but now on AS3 it's not working. I am putting all my action and codes in a ACTIONS FRAME in the top of my animation, but it is not working!
I have my Preloader on my frame 1 working, calling my animation on frame 2. The code is here (it's working):
stop();
addEventListener(Event.ENTER_FRAME, loading);
function loading(event:Event) {
var bytestotal = stage.loaderInfo.bytesTotal;
var bytesloaded = stage.loaderInfo.bytesLoaded;
var sclbar = Math.round(bytesloaded*100/bytestotal);
custom_animation.gotoAndPlay(sclbar);
if (bytesloaded >= bytestotal) {
removeEventListener(Event.ENTER_FRAME, loading);
removeChild(custom_animation);
gotoAndPlay(2);
Then I placed my buttons actions on the frame 2.
If I use the action:
home_btn.addEventListener(MouseEvent.CLICK,clickHome);
function clickHome(evt:MouseEvent):void {
gotoAndPlay(2);}
release_btn.addEventListener(MouseEvent.CLICK,clickRelease);
function clickRelease(evt:MouseEvent):void {
gotoAndPlay(2690);}
My movie pauses and no action is added to my buttons.
I get this error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
at index_Scene1_fla::MainTimeline/frame2()
If I use the action:
addEventListener("addedToStage", oas);
function oas(ev){
init();
home_btn.addEventListener(MouseEvent.CLICK,clickHome);
function clickHome(evt:MouseEvent):void {
gotoAndPlay(2);}
release_btn.addEventListener(MouseEvent.CLICK,clickRelease);
function clickRelease(evt:MouseEvent):void {
gotoAndPlay(2690);}
The movie plays complete, but I get no actions in buttons and a error in my components textinput and button (they look like shaking).
I get this error: 1180: Call to a possibly undefined method init.
I tried to use the import flash.display.SimpleButton too, but it doesn't work too.
Anyone could help me????
Thanks,
Pedro

If you can provide a clear explanation of where the buttons are and where the code for them is located that might help lead to a solution.  From what you have described already it is not clear where the code is and where the buttons are.  You should not have to use an init function if you are doing so to wait for the buttons to be loaded... they are already loaded when you get wherever they are.
For the 1009 error, it is indicative of the object targeted by your code does not exist in theframe where that code is.  SO if you have your code on frame 1 and your buttons are in frame 2, that would account for that error, as well as a few other possible scenarios.
