Flip book problem

programming flash
1

I’ve been using the flip book that is at http://www.iparigrafika.hu/. It’s great and works really well, but I’m having a problem with the buttons. The button to return to beginning works if I preview it in FlashPlayer or in a browser, but when I upload it to the internet it doesn’t work in any browser. I don’t understand why. The code I’ve used to get it to return to the first page is:

on(release) {
	_root.gotoPage(1,true);
}

The only difference between the file on my computer and the one I uploaded is that on the interent the file is loaded into another swf using:

loadMovie("portfolio.swf", this.book_mc);

Thanks
