Flash CS4 Beginner Help

Hey everyone. I apologize if I seem clueless towards all this, but I’m still new to Flash.

Anyway, I’m using Flash Pro CS4 and Actionscript 3.0, and I’m trying to create a simple homepage for the company that I work for. I have the basic outline completed (different layers for text, images, etc.) and it looks pretty nice.

Because the company I work for is a sporting goods store, I decided to create a simple animation of a basketball bouncing on the page. While I was able to create the animation, when I load the .swf file, all it shows is the bouncing animation on a white background followed by a split-showing of the homepage. I’m not quite sure why it’s doing this.

Can anyone plssible help me out? Like I said I’m pretty new to all this. :x
