Bookmark functionality in flash

Hello Friends,

i need a small help from u guys.

Actually i will tell u the reqmnt wat am looking for… i’ve done some animation in flash 8 and it was simple animation moving a movieclip vertically from keyframe 1 to 100. And i published the animation, i got an html file as well. still now everything is good. i can click the html file and can see the o/p… now when am trying to open the same html second time, i need to display a popup mentioning do u want to continue the animation from wher u stoped… on clicking yes, it has to start from wher u stopd earlier. if no, start from the beginning of the keyframe…
its more or less like bookmark functionality !!

how to achieve this !!

waiting for ur replies… i need to finish this task asap.
