Problems with DSGE model

Hi all, I am studying dsge-model simulation at PhD thesis. I am now surfacing error so it cannot drive the models due to syntax error on var and varexo command:

Starting Dynare (version 5.5).
Calling Dynare with arguments: none
Starting preprocessing of the model file …
ERROR: model1102.mod: line 2, cols 12-14: syntax error, unexpected LOG

Error using dynare (line 269)
Dynare: preprocessing failed

Without the codes it is impossible to tell.

شما اول کدها را بفرستید، بعد مشخص بشه که مشکل از کجاست.

thank you

You cannot name a variable log.

thank you

New error in my code:

Error using print_info (line 32)
The steady state has NaNs or Inf.

Error in steady (line 102)
print_info(info,options_.noprint, options_);

Error in model1102.driver (line 920)

Error in dynare (line 281)
evalin(‘base’,[fname ‘.driver’]);

what is problem?
