I want to insert three audio .swf files into my web site so that the audio plays ONLY when I click on the individual play buttons.

I inserted one .swf audio file on to my page and it auto created the place holder and I re-named the layer "click on play intro." I placed a play button from the design gallery on to my page. In the Mouse-Off group of that button, I then went to the web properties palette, to the link tab, I selected the pop-up layer and chose "play on click intro". When I preview my page, the audio file starts playing as soon as the page comes up. How do I get the audio to play only after I click the button and also stop when I click the button again. Currently, my three audio files all play at the same time when I go to preview. What/where is the setting/step I'm missing? Thanks in advance for your help. I'm using XDP 6.
