Can this be done? Rollover animation to button. Click thread for more details

Hi readers. I have a quiere involving a Movieclip, a rollover scripts and a button. I will explain my predicment below.

So within my Flash document I have a rollover movieclip that contains a UI scrollbar. My question is, can I modify this rollover script to be active until it reachs a certain frame in the animation and then become inactive so that the scrollbar works?

Or, is there some script that I can use to make the UI scrollbar active within the rollover clip?

Incidently I am using Flash 8.

I’m sorry if this sounds confusing.

If you would like to view my document, I will gladly send it, attach it, or however the system works here.

Note: This is my first post, so I apologise if I am asking explained questions.
