Drop down menus linking back to main timeline

right . . . . i have been crying over my keyboard now for a couple of days trying to find out how to do probably the most simple thing in the world . . . !!!
I have set up as per this site the drop down menu, so i have a movie file with several buttons nested in it, and this this little movie file sits in my main timeline . . . . . but for the life of me i cannot link the buttons to jump along the main timeline which the movie sits in . . . . ?
Please help as the tears are now rolling down my nose, over my chin, and dripping into my keyboard . . . . who wants to be a flash animator anyhow?
leigh.
