Image gallery problem (images not showing up)

1

so i was working on a tutorial (http://www.youtube.com/watch?v=cylX1lThTN0)

the video is great and even though it’s in as 2.0 i was able to write all the code for as 3.0

but for some reason when i type


thumb1.addEventListener(MouseEvent.CLICK, thumb1click);
function thumb1click(event:MouseEvent):void
    {
        gotoAndPlay("img1");
        trace("button 1 click works fine");
    }

what i don’t understand is that


thumb1.addEventListener(MouseEvent.MOUSE_OVER, thumb1Over);
function thumb1Over(event:MouseEvent):void
    {
        thumb1.alpha = 1;
    }
    
thumb1.addEventListener(MouseEvent.MOUSE_OUT, thumb1Out);
function thumb1Out(event:MouseEvent):void
    {
        thumb1.alpha = .5;
    }

which is written on the same actions frame work just fine but not the click that shows the pictures.

i have attached a link to download my fla (my file is too big to upload) in case anyone would be nice enough to try to help me figure it out. if it seems too involved, then i understand.

i tried everything from making sure my pictures were sent to front, checking the alpha transparency, etc …

i used trace statements on the buttons and they work fine. i did everything i could think of and i just can’t get the last step to work.

help is greatly appreciated.
