Simple Back Button

Question

I know this subject must have been asked a thousand times but
is there anyway to get a simple piece of Actionscript 3 to navigate
to the previous frame in a timeline?
The interface has 14 buttons which are the same on every
frame. Each button directs the user to a different frame on the
timeline. I need to have a back button that directs the user to the
previously view frame.
I'm new to Actionscript 3 but I did try the following code
but it didn't seem to work:
stop();
import flash.events.MouseEvent;
btn1.addEventListener(MouseEvent.CLICK, btn1Click);
function btn1Click(event:MouseEvent):void {
gotoAndStop("frame1");
btn2.addEventListener(MouseEvent.CLICK, btn2Click);
function btn2Click(event:MouseEvent):void {
gotoAndStop("frame2");
btn3.addEventListener(MouseEvent.CLICK, btn3Click);
function btn3Click(event:MouseEvent):void {
gotoAndStop("frame3");
//--- back button timeline control ---\\
function backbtn(event:MouseEvent):void {
gotoAndStop(prevFrame);
If anyone can help by directing me to some code I would be
eternally grateful.
Thanks in advance

Hi Dzedward
Thanks for your quick response . I found that the code you
gave didn't seem to work so I added the following code: I have
tried this and it seems to work in a limited capacity. I still get
an error message and it doesn't seem to go back in the same order
that the frames are view in. I'm sure it's something that I'm doing
wrong.
backBtn.addEventListener(MouseEvent.CLICK, backClick);
function backClick(event:MouseEvent):void{
MovieClip(this).prevFrame();
The error message is this:
TypeError: Error #1009: Cannot access a property or method of
a null object reference.
