flash invisible in firefox

I have a web site with a little flash component. It is referenced by an html file I have written with a little help from Dreamweaver. The deal is that when the page comes up in IE, or Chrome, the flash component works fine but it is invisible in Firefox. Can you help? This video shows what I mean

Hi,

You have this code on the swf first frame

PHP Code:

---

ifFrameLoaded(31)
{
    gotoAndStop(2);
} 


---

remove and replace it with this code

PHP Code:

---

stop();

LoadedBytes = Math.round(this.getBytesLoaded());
TotalBytes = Math.round(this.getBytesTotal());
if (LoadedBytes == TotalBytes)
{
    this.gotoAndPlay(2);
}

the way some browsers read flash is slightly different, obviously it is stopping on frame 2 with firefox and therefore not playing any further along the timeline and not showing the animation.

you might also want to put the classid back inside the object tag classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
