### error _it undefined

Posted:

**Fri Sep 30, 2011 7:35 am**I used up to today Dynare 4.1, and my model worked correctly, now I switched to 4.2 and I got the following message. Does somebody know why?

??? Input argument "it_" is undefined.

Error in ==> Problemfix2_dynamic at 46

rhs =1-params(3)+params(3)*y(3)+x(it_, 2);

Error in ==> dr1 at 153

Error in ==> resol at 128

else

Error in ==> check at 45

Error in ==> Problemfix2 at 167

check;

Error in ==> dynare at 132

evalin('base',fname) ;

Thank you
