Problem with onMouseDown

well, my problem’s kinda difficult to explain, but i’ll try my best…

i’m making a flash website, and i have four movie clips on the side of the page that act as buttons. this is the code i’m using:

[SIZE=1]about.onMouseDown = aboutDown;[/SIZE]
[SIZE=1]serv.onMouseDown = servDown;[/SIZE]
[SIZE=1]test.onMouseDown = testDown;[/SIZE]
[SIZE=1]links.onMouseDown = linksDown;[/SIZE]

[SIZE=1]function aboutDown(){[/SIZE]
[SIZE=1]_root.gotoAndPlay(31);[/SIZE]
[SIZE=1]}[/SIZE]
[SIZE=1]function servDown(){[/SIZE]
[SIZE=1]_root.gotoAndPlay(51);[/SIZE]
[SIZE=1]}[/SIZE]
[SIZE=1]function testDown(){[/SIZE]
[SIZE=1]_root.gotoAndPlay(71);[/SIZE]
[SIZE=1]}[/SIZE]
[SIZE=1]function linksDown(){[/SIZE]
[SIZE=1]_root.gotoAndPlay(91);[/SIZE]
[SIZE=1]}[/SIZE]

the only problem is, when i click on any of the links, it automatically sends me to frame 91. i’m pretty sure it’s because of the onMouseDown action, but i’m not sure how to fix it…any suggestions?
