Joe,

The compiler is telling you here that it does not recognize 
'sim_killdivb'. You should have a (logical) Fortran variable sim_killdivb.

If you follow FLASH code conventions in your Simulation files, 
 * sim_killdivb should be declared in Simulation_data, and
 * Simulation_init should USE that module, as in
     use Simulation_data: ..., sim_killDivB, ...
   or
     use Simulation_data
