URGENT HELP NEEDED! Sound/Actionscript... it MUST be simple?

hi Guys

firstly, thanks for your help on previous topics.

i have a seven-scene movie with one audio track running the length of the movie. actionscript on scene 1 frame 1 is as follows:

var my_music:Sound = new Sound();
my_music.attachSound(“TomElliot_Final_1.mp3”);
my_music.start(0, 2);
