Flash file won't replay?

Question

I am in AS3.0
I have created a linear flash file to show the steps of a user flow.
This uses a single 'next' button which navigates through the flow and at the final screen navigates back to the first screen to allow the user to view the file again.
However it sticks at screen1 and will not progress.
I have addressed the following points suggested by someone else,
1.  make sure your button listener code is on the first keyframe that contains your button.
2.  your button should be on its own layer
3.  that layer should extend to length of your timeline
4.  there should be no keyframe in your button's layer OTHER than the first keyframe.  ie, there's only one keyframe containing your button and your button exists throughout your timeline.
but it still doesn't work.
Any help is much appreciated.

What you just described isn't really following the intent of what was recommended to you.  Is there any chance you could show a screenshot of the timeline down at the scene1 end?  I am anticipating that the code that would be assigned in scene1 is not being assigned again, possibly because you miss that frame on returning, though I may be wrong.
What you might consider doing instead is to only assign one listener to that button, back in the first frame it appears in (no other keyframes on the button's layer) and have it use a variable that you assign the next screen's frame label value (call it nextSection or something).
next.addEventListener(MouseEvent.CLICK, clickNext);
function clickNext(evtObj:MouseEvent){
     gotoAndStop(nextSection);
and that nextSection variable would be declared in the first frame of a layer that also extends the length of the timeline so that it is accessible anywhere for assignment and retrieval.
var nextSection:String;
and you would assign it the next screen's frame label when you arrive at each screen.... nextSection = "screen5";
