How do I make flash mx respond to an action in HTML or ASP?

Hi

I have just upgraded to Flash MX because I thought it had a system where I could get a movie to respond to an action in HTML (or ASP), but I can't find any info on this.

What I am after is a way of controling the Flash movie from an HTM/ASP page in a frame next to the flash movie.

e.g. when a user clicks a link on the ASP page, it somehow notifies the Flash movie that there is new data available, so it can issue a loadVariables request, or better still, pass the required variables directly to the flash movie.

Any ideas??
