Shock decomposition

Hi everyone,

I am trying to do shock decomposition for calibrated model but I am receiving the following error:

My code:
stoch_simul(periods=2000,order=1, irf=0);

varobs d_y, d_c, d_i, d_x, d_m, d_w, pi, pi_d, R_f, d_y_f, d_n, pi_f;

shock_decomposition(parameter_set=calibration, datafile=myfinaldata1.xls) d_y;

My Error Message:
ERROR: c.mod:498.35-45: syntax error, unexpected NAME

Any help is highly appreciated!

I need the full file. Which version are your using?
