Error "Reference to non-existent field 'exo_nbr"

Regarding the unstable version, you can find it here: dynare.org/download/dynare-unstable[/quote]

Anyway, firtly I want to fix the problem relating to code designed by Ascari before jumping into your code.
I run this code without “clear all”, the error is below

[quote]CODE: SELECT ALL
STEADY: The Jacobian contains Inf or NaN. The problem arises from:

STEADY: Derivative of Equation 2 with respect to Variable lambda (initial value of lambda: 0)
STEADY: Derivative of Equation 2 with respect to Variable n (initial value of n: 1.04264)

STEADY: The problem most often occurs, because a variable with
STEADY: exponent smaller than 1 has been initialized to 0. Taking the derivative
STEADY: and evaluating it at the steady state then results in a division by 0.
Error using dynare_solve (line 60)
An element of the Jacobian is not finite or NaN[/quote]

Please tell me how to fix this code? What I shoud adjust to make solve this problem. Eventhough, I try to modify the parameters but the same problem still came out.
Thank Professor so much
