I had built my interface on frame 1 on main timeline with static elements.

I was under the impression that if I wanted to animate all of those elements for my main index page, I needed to do it in a new movieclip timeline and convert those items to symbols. Then set up my tweens on those layers?

When I do that, the main timeline shows through, and it looks as if I'm animating over my static interface on my main timeline. Any suggestions?
