Navbar question

im a flash noob but i managed to create a flash nav bar you press a button it drops down and five buttons appear this is all within a movie clip placed on the stage

now the question is how can i use the buttons inside the movie clip to alter the stage, i tried anchor tags didn’t work just wondering any advice would be greatly appreciated i really hate showing people how i design my websites

but if you really need the .fla just ask i guess i could post it
