I am trying to create a new fitting type with in a family of fittings. I copied a fitting type (elbow), renamed it. I then copied the original lookup table and renamed it to edit to the new fitting dimentions. When I edit family and try to change the name of the lookup table I get a invalid formula message. I have triple checked naming and the file path in the .INI file and it all looks consistant.

How do I create this new fitting?
