I'm trying to figure out a way to have a button (the source buttons) show feedback based on the current room selected and if that source is currently playing in that room. 

This is easy to do for one room:
If room=Family room AND source=tivo

But I want this to be based on which ever room is selected. So what I want is this:

If room=Family_room_AND_family_source=tivo OR room=kitchen_AND_kitchen_source =tivo OR room=m.bedroom_AND_m.bedroom_source=tivo.....then show fb state.


However, the conditional expression only allows for 'AND' or 'OR' or 'EXCLUSIVE OR'.

So any ideas?

The only thing I can think of is to instead created a button like a check mark or something for each room and source. The fb would be like the first example for each button. 

OR

I could create sepearte source buttons for every room on a subpage and show the subpage based on room selection, at which point each button would already be set to the right room and the fb would only need the current source.

But, it seems like i shouldn't have.....i know, i know...stop using SB. :)
