ok I see your problem, your master dial in the body of the conformer has the internal name Bulk, but the master dial in the V4 figure is FBMBulk that won't fly to link erc in studio, poser tends to be a bit looser about naming though its hard to figure out consistent rules as far as that goes.
as far as your erc the only erc you are showing is for valueparms in the chest. I'm not really seeing the code there for the rotate and trans dials, but as I said studio needs the internal names to match between the base figure and conformed figure
