How to change from the Button being the trigger to a link

Hi,
I have used the overlay tool - following the instructions from the http://www.flowplayer.org/tools/demos/o ... index.html

and now I want to integrate it into my site but I want a written word to trigger the overlay not a button.

On my page here http://blackpaint.co.uk/BlackPaint09/of ... index.html you can see that the button is triggering the overlay - can you help me change it so that the 'About' link triggers the overlay.

Thanks a lot
