color table

Hi,

My NCL script to test color table is like

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
begin
  wks = gsn_open_wks("pdf", "rv.KHGX.20080913_0600")
  gsn_define_colormap(wks,"GrayWhiteGray")
exit

I got error
[yli@cirrus ~/files]$ ncl rv-contour-KHGX.ncl

fatal:CvtStringToCmap:Unable to convert string "GrayWhiteGray" to ColorMap

Any suggestion is welcome.
