Interactive Map (require some help and direction)

I have developed an interactive map for a client which is working very well indeed. I have done most of the interface which acts very similar to the windows platform interface.

On one of the windows includes a map, on this map is a serious of postal codes, so when the user hovers over one of the locators (i.e hotspot so to speak, or button) a popup window appears with information that I have set up with of course some help and dedication. Except the client now requires the colour coding of sections or hotspots on the map.

So my thoughts were to have a key with five colours, each with a text description alongside. And when the client clicks a hotsport they can change the color of the hotspot by selecting a colour from the key.

Hope this makes sense so far. But also, this information needs to be stored in the swf file, I know this can be done, but a little unsure how to achieve this with my system.

Can anyone advise of such an action into the right direction of solving my problem.

Cheers to any that help guide.

A simple sameple would be totally rad.
