Always remember, when you copy a button to add new logic to it, you have to give it a new join number, and when it asks you if you want to keep the existing programming click NO unless you want to keep the existing programming as well. It would work great for "Group" volume but not for "zone" volume control.
Another thing to check is make sure your buttons don't have any template data on them. Even if you have copied the volume buttons and assigned new joins and different programming the template data will still be present. This is where I ran into situations where my buttons would work once or twice but once I created an archive and opened from the archived document my programming was all screwed up. Deleated the template data and all is fine.
