This may not even be possible but…

I’m attempting to make an interactive floor plan of the building that I work in.
I’ve got a map that users can point to an office and mouse click, which sends a number to a calculator. In this way, management can calculate the amount of floor space their department is using. (silly, I know, ask the bean counters) I’m using “hotspots” to mark the offices, I’ve deleted the href and put an OnClick in it’s place in order to send a pre-determined square footage number to the calculator.
Here’s the question…Along with sending a number to the calculator, I’d like the ‘hotspot’ area to be highlighted after getting clicked.
Help?
