Help with DSGE model

I am trying to reproduce the results of this article … p06-34.pdf (the equations are in the appendix), however, I am always receiving an error message. I’m newbie on dynare so if anyone could give me some advice. that will be great.
aar.mod (5.24 KB)

Always post the error. It is

[quote]ERROR: aar.mod:108.33-52: Symbol rhopi is being treated as if it were a function (i.e., takes an argument that is not an integer).

Thus, there is a problem in line 108, column 33. Your forgot a * after rhopi.

you were right, so I fix this problem (thanks), but now I receive this message

??? 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
