Stuck on a link problem that im sure isnt hard to fix :/

Im not the best at flash i have to say. i am struggling through a project for class on our library. i made 2 maps for interactiveness where the user rolls over a particular area and they see some information about it to the side.

Only problem is when you move the mouse to the right it goes crazy and starts picking loads of random buttons. dont have the smallest idea why?!?!

i cant attach so i put it up on the net, if you would please have a look at it and give me some pointers i would be eternally grateful!!!
