Trouble with Scrollpane Component

This is a little difficult to explain clearly, but I’ll try my best:

On my site, I have a swf file that is to load above my main timeline, and I am using the scrollpane component in the loaded swf. The problem that I’ve encountered involves what I am trying to achieve inside the movie clip. I have various buttons with the movie clip that, when clicked on, opens up to reveal some content and closes back up when it is clicked on again. However, the scrollbar does not update to the new content size, so you cannot see all of the content nor the rest of the buttons.

How can I tell the scrollbar to listen to the movie clip and adjust to any changes that it has?

The buttons within the movie clip direct to an animation within the movie clip.

I may post the swf file when I get home if this is too confusing to follow.
