Few beginners problems with Flash

Hello,
I have decided to start learning flash, and I have gotten pretty far in the last 2 days just from reading tutorials on here and actionscript.org.

Now I have run into a problem that I cant find a tutorial or reference for.

I am trying to create a scrollable window, but all of the pieces are custom.

I made the background, and the “scroller” and the mask, but I cant find out how to make it interact.

Here’s the link:

Here’s my FLA
http://www.voiceman.com/new/clients.fla

None of the buttons work yet, as this is the first page I have started.

Thanks for your help…

Colin

Im looking at a few tutorials, and I think Im going to run into trouble because my buttons are in the same swf as my contents.

From what I understand, I should be able to do this, but none of the tutorials I have found are mentioning an option to do it this way.

So should I be removing my buttons and starting over?

maybe making them on the Mic on the right, and having that whole part as a different swf?
