I have started a new project but cant figure out how to fix a couple css conflicts with IE and FF looks great in FF but not IE.

I have managed to get one of 2 scripts added but am having difficulty adding the second one as I can get a else/if to work

Can see what I have got so far here I need the mp3 part added in (same script as here). If you are interested in doing this just send me a PM with a price in mind
