Placing a button inside a movie clip that loads when you roll over a button

I have set up a series of buttons. I want a movie clip to load when you click on any of the the buttons. I also want the user to be able to click on a button the movie clip that loaded if they wish to load a webpage.

The way I have it set up now is that when you click on any the main button, a “tell target” action to go play a specific frame of a really long movie clip that contains all the mouseovers. This works fine. But it is the button within the movie clips that are not working.

Can anybody help?
