'plotgrids_var.f90 error' with 'plotgrids_new.ncl'

[Liquy]

Hi, all:
I got an error when I was drawing domains with the file 'plotgrids_new.ncl' .
I have plotgrids_new.ncl in /fs2/home/sfhua/liqiuyang/WPS/util, I have namelist.wps in /fs2/home/sfhua/liqiuyang/WPS.
when I run this script('plotgrids_new.ncl') under WPS directory, where my namelist.wps is located, (ncl util/plotgrids_new.ncl)
it says 'At line 66 of file plotgrids_var.f90 (unit = 10, file = 'namelist.wps')
Fortran runtime error: Invalid string input in item 0',

I can't find this file（'plotgrids_var.f90'）, so I don't know what's wrong.
This is my plotgrids_new.ncl:
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRFUserARW.ncl"

begin
;

; Check the version of NCL
version = systemfunc("ncl -V")
if(version.lt.6.2) then
print("You need NCL V6.2 or later to run this script. Try running plotgrids.ncl. Stopping now...")
return
end if

; We generate plots, but what kind do we prefer?
type = "x11"
; type = "pdf"
; type = "ps"
; type = "ncgm"
wks = gsn_open_wks(type,"wps_show_dom")

; read the following namelist file
filename = "namelist.wps"

; Set the colors to be used
colors = (/"white","black","White","ForestGreen","DeepSkyBlue","Red","Blue"/)
gsn_define_colormap(wks, colors)


; Set some map information ; line and text information
mpres = True
mpres@mpFillOn = True

Just a quick check to make sure that:
(1) you have namelist.wps in your WPS directory? and you have WPS/util?
(2) you can run other NCL scripts? --- this is to make sure your NCL is installed correctly

Please delete the following two lines:
pole_lat = 90
pole_lon = 0

Then try again. Let me know if you still have the same problem.

I deleted the following two lines:
pole_lat = 90
pole_lon = 0
and tried again. But I still have the same problem.

Yes.
I have namelist.wps in my WPS directory, and I have WPS/util.
I can run other NCL scripts.
