Sending Flash Choices to HTML Forms

I have created a flash movie whereby a customer chooses a color for one of our products.
I want to design script that loads the choice into an html form with javascript.
The page can be found at http://www.asanaclimbing.com/disturbedEnlarge.htm

The flash movie is operating, but does not communicate with the html forms.
I have tried some javascript to get it to work, but to no avail.
Presently my customers have to choose the color in the Flash movie and then again in the html code which is a pain.
Can anyone point me in the right direction?

You can use the flash ExternalInterface.call() to call a JS function and pass vars to that function .... the documentation is here

Thanks so much,
Do you have a good resource for getting the variables from the javascript to the html forms?

I think i understand what your asking.... here is a link to a page on how to do a Javascript POST.... if this is not what you mean please just let me know
