Can't get External API to work in IE7

Question

I'm trying to get a Flash Ad to call a Javascript function in
an Ajax page. I'm using ActionScript 2.0 ExternalAPI to call a
function in the page that adds an item to a shopping list. I can
get this to work in all browsers except IE7. It even works in IE7
when I put this Ad alone in a basic html page, but as soon as I put
it in an Ajax page it does not call the function in IE7.
I appreciate any help or suggestions

Answer 1

Thanks for the input. I'm not familiar with Ajax so it helps
to know if there are any known issues. I assumed it was an Ajax
issue because the same ad works in a non-ajax web page that uses
frames. The ad is being served through DoubleClick, here is the
rich media code that embeds the Flash Ad:
<!-- This is DART's Rich Media code template. It basically
checks user's flash version and browser, embeds flash creative in
page or serves fall back image if user does not have the required
version of flash player. -->
<SCRIPT LANGUAGE=JavaScript>
