Slideshow not resuming after certain buttons are used?

Question

Hello,
I have this slideshow that I'm so close to having completed, but there's one issue I'm having with it not resuming after certain buttons are used. I've tried to figure out what could be causing this but I just can't see what it could be. I feel I'm so very close to having this completed if it weren't for this one issue.
In the slideshow buttons '1' and '2' work perfectly, however buttons '3' to '6' are not working completely as they should. During the slideshow, as it plays through the slides if you click on button '1' or '2' you are taken to the corresponding slide and then the slideshow automatically resumes, which is correct. However, if you click on any of buttons '3' to '6' you are still taken to the corresponding slide, but the slideshow does not resume and stays on that particular slide. I've looked over the Action Script 3 code several times and I just don't see what could be causing this but I'm not too experienced so there could be some error, no matter how minor, that I am missing.
I've attached the file and if anyone has any advice at all or can help in any way I would REALLY appreciate it!
Thank you,
William

In looking at the post I just made just now, I notice my attachment didn't come through. I'm not sure why this happened, but here is the code I'm using for the buttons:
btn1.addEventListener(MouseEvent.CLICK, btn1ClickHandler);
function btn1ClickHandler(event:MouseEvent):void
    gotoAndStop(10);
play();
btn2.addEventListener(MouseEvent.CLICK, btn2ClickHandler);
function btn2ClickHandler(event:MouseEvent):void
    gotoAndStop(55);
play();
btn3.addEventListener(MouseEvent.CLICK, btn3ClickHandler);
function btn3ClickHandler(event:MouseEvent):void
    gotoAndStop(105);
play();
btn4.addEventListener(MouseEvent.CLICK, btn4ClickHandler);
function btn4ClickHandler(event:MouseEvent):void
    gotoAndStop(150);
play();
btn5.addEventListener(MouseEvent.CLICK, btn5ClickHandler);
function btn5ClickHandler(event:MouseEvent):void
    gotoAndStop(210);
play();
btn6.addEventListener(MouseEvent.CLICK, btn6ClickHandler);
function btn6ClickHandler(event:MouseEvent):void
    gotoAndStop(259);
play();
And here is the code I'm using for slide images:
link_1.addEventListener(MouseEvent.CLICK, link_1ClickHandler);
function link_1ClickHandler(event:MouseEvent):void
    navigateToURL(new URLRequest("http://www.debcosolutions.com/en-us/categoryredirect.aspx?categoryid=gifts%20worth%20givin g%20can&pricing=cad"));
link_2.addEventListener(MouseEvent.CLICK, link_2ClickHandler);
function link_2ClickHandler(event:MouseEvent):void
    navigateToURL(new URLRequest("http://www.debcosolutions.com/EN-US/redirect.aspx?ssk=CU7323&pricing=CAD"));
link_3.addEventListener(MouseEvent.CLICK, link_3ClickHandler);
function link_3ClickHandler(event:MouseEvent):void
    navigateToURL(new URLRequest("http://www.debcosolutions.com/EN-US/redirect.aspx?ssk=CL7292&pricing=CAD"));
link_4.addEventListener(MouseEvent.CLICK, link_4ClickHandler);
function link_4ClickHandler(event:MouseEvent):void
    navigateToURL(new URLRequest("http://www.apple.com"));
link_5.addEventListener(MouseEvent.CLICK, link_5ClickHandler);
function link_5ClickHandler(event:MouseEvent):void
    navigateToURL(new URLRequest("http://www.debcosolutions.com/EN-US/redirect.aspx?ssk=CL7306&pricing=CAD"));
link_6.addEventListener(MouseEvent.CLICK, link_6ClickHandler);
function link_6ClickHandler(event:MouseEvent):void
    navigateToURL(new URLRequest("http://www.debcosolutions.com/en-us/categoryredirect.aspx?categoryid=shocking%20deals%20-% 20cl&pricing=cad"));
