NAN values in result

Hi friends,
Finally I can run my model, but I have a new question from you:
The output of my model, some values marked with “NAN”, why is that?

Your timing is wrong. There are no forward looking variables in your model.

Hi friend, Thanks for your answer.
Now I have 4 forward-looking in my model but NAN values appear in my result again. what’s your suggest for solve this problem?
Thanks a lot

Correct your model. The variables with NaN are variables that do not move at all during your simulations. Add e.g.

after stoch_simul to see this. There must be a mistake in your model.
