I'm trying to make a flash movie to go on one of the pages on my website. There's this one action (example can be found on http://www.johnnypanic.com/theband.htm) where when you click on one of the band member's top 5, another screen pops up with their top 5 things in it. How would i go about getting something to pop up like this after clicking a flash button? Any help would be greatly appreciated.
