Help with sound (renamed)

I tried performing this [size=2]tutoria[/size][size=2][color=#003366][font=Verdana]l:[/font][/color][/size][font=Verdana][size=4][color=#003366]
[font=Verdana][size=4][color=#003366] a Volume Control Slider[/color][/size][/font]

I added my song to the library and exported the file to my desktop. The swf file plays perfectly on my desktop…the slider, stop and play button all work. The problem arises when i upload to website. It appears on the site but it doesnt play. It only says that it is downloading song and just stays like that for a considerable amount of time. I cant understand why it works on the desktop and not on the website. I think it is a quick fix… can someone can just tell me what i am doing wrong?
