Hi,

I have never used ADMMacros, but looking at the code, it looks like DETG_PSI4 is defined in DETG_declare.h, which also declares the variable it names (CCTK_REAL DETG_PSI4), and this header is included by UPPERMET_declare.h, which is included by TRRICCI_declare.h.  So as far as I can see, if you include TRRICCI_declare.h, you should get the declaration of DETG_PSI4, which is detg_psi4.

One thing to check is that you have included the header files in your function, not at the top of the file with the other includes.  Could you post your code, or a small cut down example which we can use to reproduce the problem?
