Creating a simple photo gallery.. buttons not working.

Question

Im trying to create a photo gallery that when you click on the thumbnail image you get a blown up image on the screen. The user will then hit the little "x" button to return to the thumbnail page.
I have attached pictures of what they look like. My issues is that when the user clicks on the little "x" nothing happens on images 2-5. It works fine on image 1. I have fiddled with the code, creating different buttons, using the same button both with different instance names and with different. Still does not work. I do not get any error messages during test either. Im at a loss. Please help!
Here is the code as it stands: (ActionScript 3.0 using Flash CC)
function go_back1(event:MouseEvent):void {
  gotoAndStop(1)
close1.addEventListener(MouseEvent.CLICK, go_back1);
close2.addEventListener(MouseEvent.CLICK, go_back1);
close3.addEventListener(MouseEvent.CLICK, go_back1);
close4.addEventListener(MouseEvent.CLICK, go_back1);
close5.addEventListener(MouseEvent.CLICK, go_back1);
close6.addEventListener(MouseEvent.CLICK, go_back1);

I think the problem lies in skipping the frame where the button gets the listener assigned to it.  If you are at frame 1 and then jump frame 5 or beyond you skip the code that would be assigned in frame 4.
Try the following.  Have the close button start from frame 1, but in frame 1 make it invisible.  Also move the listener code and event handler function there as well
          close1.visible = false;
          function go_back1(event:MouseEvent):void {
            gotoAndStop(1)
          close1.addEventListener(MouseEvent.CLICK, go_back1);
Then in whatever function(s) you have for going to one of the large picture frames include the line to make close1 visible.
        close1.visible = true;
