I have a Flash movie that automatically opens another Flash movie inside it. The main swf has a "Start" button at the bottom. When I click the Start button I want to unload the swf that loaded automatically (as a placeholder) and load a new Flash video swf. I'm doing this to create a placeholder for the video. I don't know what code I need to use on the button to unload the automatic swf and load the new swf video.
