Gtyp error in paragon

I'm creating a structural profile specification in paragon but after typing [LEFT][COLOR=#222222][FONT=Verdana]NEW SPCO /RHS-300x200x12 CATREF
/RHS_300x200x12, [/FONT][/COLOR][/LEFT]
GTYP is not added and even when i go to edit answer the GTYP gives error such that after in design module, beam and column won't launch as Gtyp is not defined.

What about catref, whether GTYPE Defined in catref?

Check whether the spec in which your are addgin does not show read only on top header of spec , or try by copying the spco and fiiling its attribute
