Capturing a javascript src ad zone text in flash

Hello all,

I build flash web sites and have only a limited understanding of javascript. I am trying to monetize a flash page that I have built for myself and is getting an increased traffic. The page has to be flash as it is based on flash dynamic graphic capabilities. Besides I prefer to integrate and customize the ads into my page rather than use standard ad zones offered by the ad networks. I have a permission from a small ad network to convert their ads to flash but I was not able to do it myself. They use a standard java script src code for creating their ads.
It looks approximately like this:

<SCRIPT LANGUAGE=“JavaScript1.1” SRC=“http://bdv.Advertiser.com/Advertiser.dbm?pid=22222&bid=111111” type=“text/javascript”></SCRIPT>

They require though that the capturing will be done in a way that allows them to monitor my page. I can publish Flash player 9 so I can work with ExternalInterface.call

Any hints on how to translate the code to Flash and how to change the html code will be helpful. I am also willing to pay someone who is interested in working with me directly via Email correspondance on properly placing the code. My Email address is newventure@live.com

Many Thanks,

Mark.
