Flash and DHTML Working Togather

Hi, Soon I will be doing a school project where I must create a web page where I must use Flash and DHTM and get the two to communicate with eachother. Flash controlling DHTML content and vice versa. I was hoping to get a head start but an having trouble finding information and how to get the two to work togather. Im quite comfortable with Flash and AS but have not used DHTML before.

If anyone has any links, information or examples of the two working togather it would be appreciated.

Cheers.
