Scrolling Menu problem

I made a scrolling menu a lot like the one in the tutorial only it scrolls up and down rather than left to right. The menu works right but when I try to put it on a website it won’t move at all. I exported it as an animated gif and then loaded it onto a tripod site. Is there something else I have to do to get it to work?

                                Thanks

you have to export it as a swf because if you export as gif the image is plain and all the actionscript is lost
