Anybody.... please!!!!!! I'm begging you, please help....

I've read about them, looked through tutorials ... but now I'm still stuck - got a deadline coming up and have a complete blank on how to center my flash site in the browser window, regardless of which size monitor it is being viewed on....
I've done a flash site (600x400px) and I'd like to put it on the html page in Dreamweaver, setting it up so when viewed - the flash content will always end up in the center of the monitor/browser window, on a small screen the same as on larger monitors.
I would REALLY REALLY REALLY appreciate any help on this!!!!!!!!!!!!!!!!!
Thanks for listening

Happy flashin' Prisca
