Using a timed function to reset a movie clip

Hi there,
This question is a little easier than my last one, but I still need help with it. I am working with something where a movie clip is called on to display addresses on different frames. When a user clicks on the dot for a certain address, it calls the addresses movie clip and goes to that address. What action script can I use to make it so that if no one clicks on the address information in a certain time period, the movie clip that has the addresses in it goes back to its first frame which is blank?

I am still very new to actionscript, obviously, so any help is very welcome and appreciated.

Thanks, Jeremiah
