Dynamic multiple choice activity

I've been working on a multiple choice problem. This is somewhat of a side item to the GA Flash Map, although the dynamic part of it may be reusable when I give the user control of the map.

Here's what's happening with this multiple choice movie. I have a basic multiple choice interaction that is available for anyone's deconstruction and reuse here: multi_plus.fla. This requires knowledge of actionscript and an ability to get inside the Flash file to manipulate the contents.

What I am trying to achieve with this dynamic multiple choice activity is the ability to hand the .swf file to someone and give them instructions on how to load in their data. This ties in with an ongoing concept of mine to make items modular and reusable. Putting more thought to this... it really becomes a SCORM type of thing.

So, I have the file working better now than it was last weekend. I am able to load a question and any number of answers into a file. The answers change a key variable, so in theory, the answers can be checked. What I haven't been able to accomplish is clearing the radio buttons. I haven't attempted to check answers or progress to the next question.

Here's the file so far: multi2.html. It looks pretty simple, but keep in mind that everything is loaded via actionscript, in such a way that it will be editable without having to know how it works.
