DFTB ERROR

[irti]

Dear CP2K users,

I am trying to do DFTB calculations with CP2k. I am getting this error 
message

**************************************************************************
 *** 01:22:04 ERRORL2 in input_section_types:section_vals_val_get       ***
 *** processor 0  :: err=-300 Value requested, but no value set getting ***
 *** value from keyword GMAX of section EWALD                           ***
 **************************************************************************

Here is my DFTB section 

METHOD DFTB
&DFTB
        HB_SR_GAMMA        T
        SELF_CONSISTENT    T
        DO_EWALD T
        DISPERSION         T
        &PARAMETER
          PARAM_FILE_PATH  ./dftb_params/scc/
          PARAM_FILE_NAME  scc_parameter
          UFF_FORCE_FIELD  uff_table
        &END PARAMETER
      &END DFTB

When I tried

 DO_EWALD F

then it ran without any error but gave poor energy values.

Please help me about this particular error.

Thanks.

Best, Irtaza
