Need serious help with _root, _parent, etc

Ok

I have a movie clip, inside of a movie clip

I need to control the second clip (the one inside of the first) from the main timeline. How do I go about doing this? I’ve tried adding _root. and _parent. to the clip name but no go. Is there some other way to specify what I’m trying to do?

btw I’m using flash5, but I just assumed it’s the same as mx

Awesome! Thank you very much!!!
