Okay, so I got the music to play before with no problem. But I had to fix it because it would start replaying when I went to the menu of the Flash video. So there would be two songs playing over each other.
Then I got help from my teacher. He created a new symbol, and pasted the music file into it. That worked. But then I added a new menu in the beginning that you wouldn't be able to return to. I tried to put the music there again, not as a symbol. But then, it was just a flat line. If I extended the end of the thing, the music showed up. But it was set up in a way that the music started AFTER all my flash frames.
Here's what it looks like normally, when I don't pull the frames further:http://i835.photobucket.com/albums/zz277/Enacragus/Picture2.png
