Hi Jenny - If you have not already figured this out - getting movies to play out of webpages has long been a detail-tricky, problematic challenge - expecially when you want your page to play in EVERY webbrowser on EVERY platform. But, just looking at your code, I believe the path to the file itself is suspect. I'm not sure why there is a question mark infront of the filename. You might want to get familiar with relative folder addressing. If there is a folder (named 'audio_files') with the audio file at the same level as the HTML file from which you are executing, you could refer to it as "./audio_files/13Jan2012.mp3". Remember that alphabetic CASE COUNTS in many such circumstances and that not all characters are 'allowed' - or they may be interpreted in different ways than on your desktop - in web URLs.
Below is an example of what I normally do with video files (although audio would work the same) in my webpages:
