There we go, now it's working!
EDIT: However, just thought of something. In my game, I'm planning on having multiple different actors. They won't all be in the party at the same time, as it's more of a "this person's campaign then this person's then this person's". But if I have the gauge set to just that one actor's ID, then once gameplay switches over to another actor, it wouldn't work because it'd only be showing data for that one actor.
