Making a rollover map

Im creating a part of a presentation for a friend and have got a little stuck.

Here is what i have so far: http://nanothree.net/projects/tom/brad.swf

As you can see parts of the map say above the growing piece, i think this is due to the order i put them to the stage with. They are all on the same layer. Would it be possible to have them appear above all other objects on mouse over.

Thanks

can u post ur code

or u can use this code
