Hi,anyone can solve the problem in the following?

When I Run the model,it Shows:

model_diagnostic: the Jacobian of the static model is singular
there is 1 colinear relationships between the variables and the equations
Colinear variables:
Sn
Colinear equations
90 91 92 93

The message is pretty clear: one equation is the linear combination of the others, so you should remove it.
