Flash reading Html

[Txar?n]

Hi, I am trying to make a baner that will be on every htm page of my site, but
will start playing a diferent frame at every page:
Movie.swf at index.htm will play frame 2
movie.swf at portfolio.htm will play frame 5
and so on.

How can I make the flash movie to check on wich htm is is located? :confused;

Thanks
