This project uses scripts and Variables to keep track of WHICH of the  two menus generated the request to play the Track.

• Each Menu uses a SetMenu script to establish a value in GPRM 0 that corresponds to a Menu you are currently in.
• The Original Menu sets the value to 1, and the Alternate Menu sets the value to 2. 
• When a button is pressed, the button navigates to the selected Track,
• When playback is finished, the “Find The Source Menu Script” determines the source of the play request, by testing the GPRM
• 0 for its current value –
