Hi, my mdoel could not converge making acheiving steady state difficult the error it displays goes thus;

??? Error using ==> print_info at 57
Impossible to find the steady state. Either the model doesn't have a steady
state, there are an infinity of steady states, or the guess values are too
far from the solution

Error in ==> steady at 92
print_info(info,options_.noprint);

Error in ==> kk1 at 450
steady;

Error in ==> dynare at 120
evalin('base',fname) ;

Please can anyone tell me the easiest way of resolving this error?

thank you
