I am attempting to program the TSU9600 for a multi room installation. I would like to create a global variable for the selected room, for use in the volume control of an audio matrix system. I have tried declaring the global in the HOME properties -advanced tab as follows

var Room
System.setGlobal(Room) = 0 // Reset to Room to 0 every time home page is visited

I get errors when I try to set the global variable to other values, and when I try to reference this global.

I'm new to JAVA so would appreciate someone pointing out my errors.
