Dynare forums

I am trying to replicate an incomplete markets model. I have tripled checked the equations and everything seems to be fine. Nevertheless, I obtain an error message from inside dynare.

It is known that these models policy function do have an unit root. Moreover, there are multiple steady states. I am telling dynare the steady state.
But either in the command check or stoch simul the following error message appears. (Sticky is the dyn file)
*****************************************************
??? Subscript indices must either be real positive integers or logicals.

Error in ==> dr1 at 139
b = jacobia_(:,k0);

Error in ==> resol at 48
[dr,info] = dr1(dr,check_flag);

Error in ==> check at 18
[dr, info] = resol(ys_,1);

Error in ==> Sticky at 106
check;

Error in ==> dynare at 26
evalin('base',fname) ;

Please find enclosed a zip file containing the dyn file and the m file to compute steady state.

Thanks to the help of Michel the problem was solved. There was a variable in the model that was mistakenly appearing at t-1 only.

"
Note: I identified the problem by looking at global variable iy_ that tells which variable appears at which lag. The variables are ordered in alphabetical order."
