Me neither... BUT... I finally figured out where I was going wrong....! Yippppeee...! Looks like my ERC WAS working all along... problem was I had the deltaAddDelta value set so low that it wasn't making a visible adjustment in Poser. Changed that value from 6 to 400+ (still have to fine tune final value) and... BINGO... it works fine. Many many thanx to everyone for their suggestions and help. I'm off to sort my bed out :)
