API google map all over my pages

Hi,
I am a AS3 and Flash CS4 newb user. I created a simple website which's structure I explain below:
the website has 4 main layers:
1- Houses my script
2- Houses my menu which has movieclips as bottons
3- Houses the content of the pages (1 movie clip with 7 frames for different  content)
4- Houses my background design
On the movieclip of fram 3 I inserted 2 layers:
1- Houses my AS3
2- Houses the different frames of the movie with different content)
The problem is that I inserted my script on frame 5 of the AS3 layer for it to display a couple of google maps on the content layer of the movie clip. When I test the website and navigate to the frame 5 where the maps are being displayed, everything displayed ok BUT when I navigate away from that frame the google maps do not go away. They simply go on top of the content of the rest my my movieclip frames overriding whatever content I have.
Here is the code that I used for to insert the google maps. Any help please?
