How to go back to the main scene in flash

Q: Once an external SWF file is loaded with the main movie there is another button that I would like to close out of the SWF file and go back to the main movie.

A: If the button is within the loaded movie you should use this action script:

on(release)
{
this.unloadMovie();
}

If the button is within the main movie, please use the following script:

on(release)
{
_root.Contents.unloadMovie();
}
