# Can't obtain the posterior distribution

hello please help me I can’t obtain the posterior distribution this is my code and my data.m and below I tell you the error I obtained can you find a solution for me? thank you
//

alpha = 0.33;
beta = 0.99;
delta = 0.023;

epsilon = 10;

model;
(1/c) = beta*(1/c(+1))(1+r(+1)-delta);

y = (k(-1)^alpha)(exp(z)l)^(1-alpha);
w = y

estimation(datafile=y,mh_replic=2000,mh_nblocks=5,mh_drop=0.45,mh_jscale=0.8, mode_compute=4);

the error that I obtain

Your code is wrong. You have to provide the name of the data-file (which is not y.m) after

`datafile=` Moreover, never name your data-file data.m
