Dynare forums

Okay so I am running the following code for Chapter 09 of ABCs of RBCs. But I am getting the message:

??? Error using ==> var
Too many input arguments.

Error in ==> mgafri2 at 6
var y c k r h w m p la g;

Am completely new to MATLAB and dynare. I installed dynare and added it to path.

My code is:
