Those codes worked perfectly. Saved me a ton of 'testing' time. Thanks!

I ended up doing a "room picker" home page, followed by source selection pages for each room. I used flags to track what room you were in and made the home button take you back to the room source selection page (which had a little "Rooms" button at the top to take you back to the "room picker" page).

I got the ultimate compliment from the customer when he said "That seems easy enough"

Thanks all
