On my HTML Site page, I have 4 seperate flash components each in theire own HTML Frames.

I need to have somekind of information exchange between them to coordinate what goes on in the middle HTML Frame depending on what the user selects with the buttons of the different Flash.

The Top frame is a gametype Flash button.
The Left Frame is a Flash menu for News, Projects, ...
The Bottom Frame is a Screenshot Flash Button.
The Right Frame is something else under work.
The Middle Frame is where the right HTML will be loaded depending on what game the user wants and for what sort of info (news, projects, ...).

So I need my Left Frame to communicate with the Top Frame. I also need my Bottom Frame to communicate with the Top Frame.

I only need to pass on 2 variables between them : GameType and ActionType.

I'm thinking of several ways like CGI variables or somekind of Flash Player shared pool of custom variables for all *.SWF files on the same HTML page.

So, is there a way to do it ?

How ?
