Need help - trying to make an extension to a given NK model

Steady state

Hello everybody, I am attempting to add government spending as an endogenous factor to a basic New Keynesian model, but I have encountered errors:

Error using print_info (line 33)
The steady state has NaNs or Inf.

Error in steady (line 143)
print_info(info,options_.noprint, options_);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error in CodeFinal.driver (line 564)
steady;
^^^^^^
Error in dynare (line 308)
evalin(‘base’,[fname ‘.driver’]);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Have I made a mistake while coding, or can my steady states not be solved regardless of the code? Is the idea itself not feasible/fundamentally incorrect? Any help is greatly appreciated. Thank you very much in advance.

Thank you very much for your help sir, I was naively unaware of the importance of the ordering of my code. Have a great day.
