Button insided of Movie Clip

Please excuse the simplicity as I’m *relatively *new to Actionscript. I basically want my navigation to be hidden until you rollover top 1/4 of page. Once rolled over, navigation shows itself, then on rollout it disappears.

I have placed my navigation inside of a movie clip. When you rollover the movie clip, the nav shows itself, then when you rollout it disapears exactly as planned…

Now, when I add an actual navigation button inside of the movie clip and rollover it, the main navigation plays out and disappears.

How can I have the two nested buttons play nice together and give me the desired effect?

Any guidance is really appreciated. :beer:
