Hello every one!
I have a very simple model. It shows these errors when I run it. I cant understand how can I solve it!
These are the errors:

Error in ==> check at 76
print_info(info, options.noprint);

Error in ==> Simple_model at 248
check(M_,options_,oo_);

Error in ==> dynare at 120
evalin('base',fname) ;

could you please help me?
Any help would be appreciated.
I can not attach the file so I write all bellow!

model_diagnostics says
model_diagnostic: the Jacobian of the static model is singular
there is 3 colinear relationships between the variables and the equations
Relation 1
Colinear variables:
yy_o
yy_T
ii_o
ii_T
tt
ll_o
ll_T
qq
kk_o
kk_T
Relation 2
Colinear variables:
yy_o
yy_T
ii_o
ii_T
tt
ll_o
ll_T
qq
kk_o
kk_T
Relation 3
Colinear variables:
yy_o
yy_T
ii_o
ii_T
tt
ll_o
ll_T
qq
kk_o
kk_T
Relation 1
Colinear equations
1 2 3 4 6 7 8 9 11 12 13 14 15 16 17

Relation 2
Colinear equations
5 9 12 13 18

Relation 3

Please search the forum. Often it means that either there is a unit root in your model or you are missing an equation while having a redundant one in the model (usually due to Walras Law)
