Question about buttons in the script

So, I have a file where I have the action script all ready and working, and all the buttons working.  The whole file works perfectly.

But, when I make a new file and copy and paste the action script and buttons, it doesn't work!  I have the EXACT same script, and the file setting are the same as well.

Is it because I copied and pasted the actual buttons?  Or is it because of the script?  I've created new buttons, and modified the script to use their instance names, but that doesn't work either.

The weird thing is that 1 of the buttons I copied and pasted work!  I have 4 buttons total, and 3 of them change the FPS of the stage using this code -

button1.addEventListener(MouseEvent.CLICK, goNormal);

function goNormal(event:MouseEvent):void {

  stage.frameRate = 24

The button that does work uses this code -

button4.addEventListener(MouseEvent.CLICK, goEnd);

function goEnd(event:MouseEvent):void {

  gotoAndStop(1,"Scene 2");

}

I've even changed the functions around.  I've spent the last 4 hours trying to fix it, but apparently I can't.

Thanks!
