Can someone PLEASE help me solve this mystery?

Ok, a few weeks ago I had some difficulty getting an audio player to work properly on my site. I tried a few tutorials, and I finally got it to work, except for one thing - when I put a video on my site, it interfered with the sound of the video. If a person tried to play the video, and the music was still on in the background, when they turn off the music, the video also turned off… which means they would have to re-start the video, and that’s not the way it should be.

So, to avoid all the hassle, I purchased a sound player maker, which I thought would solve all these problems… but it hasn’t, I can’t get the sound player (which is an external swf) to play on my site. It works on its own, when I test it in a browser window… but it doesn’t play on my site.

Here is the code I have now (I changed the url for display purposes)

holder_mc.loadMovie("http://www.mysiteurl.com/flash/mysoundplayer2.swf")

I just want the player to work. And hopefully not interfere with the other sound on the site, like the old one did.

Please help?!!!
