Hmmm...that's odd. I can reliably make a body part or prop control another that's one level above itself if both are part of the same IK chain, but I can't get higher up than that and the IK has to be there. I use Poser 4. Are you by any chance using Pro Pack? The inability to control things at a higher level in the hierarchy seems to be a refresh problem of some sort. The effect of changing the master dial only seems to be noticed at certain times, like when you switch to a different camera or use undo. I almost never work with any type of master other than a valueParm though, so it could be that ERC works more reliably with rotation dials or something.
