Re: fatal:Undefined identifier: (gsn_csm_contour) is undefined, can't continue

Hi,
Thanks for your help, it is working but inside the figure (attached)
contours are missing at some places. Please your advice/suggestion will be
appreciated. some part of script and print summary is attached herewith.here
i'm using wrf data.
thanks again,
wei
