Can someone see my code and tell me what is wrong? I have 70 variables and 70 equations but it tells me that there are 56 variables and 69 equations. what is wrong?

You misread the message. This is for the block decomposition of the model, not the overall model:

Finding the optimal block decomposition of the dynamic model…
2 block(s) found:
1 recursive block(s) and 1 simultaneous block(s).
the largest simultaneous block has 69 equation(s)
and 56 feedback variable(s).
