avg function-Number of subscripts do not match number of dimensions of variable

 Hi,   I want to calculate monthly mean daily variation. The files are splited every hour. When I use avg function, I have this error 'Number of subscripts do not match number of dimensions of variable,(1) Subscripts used, (2) Subscripts expected'. Can anyone help me?Thanks. The script and error are as below.   Best, Guo   begin   fil0 = systemfunc("ls /d1/model/guoz/CTL/HRLDAS_MP/Run/Glees/200907*.LDASOUT_DOMAIN1")+".nc"   fil1 = systemfunc("ls /d1/model/guoz/BT/HRLDAS_MP/Run/Glees/200907*.LDASOUT_DOMAIN1")+".nc"   nfl = dimsizes(fil0)   S_CTL  = new((/nfl,1/),float)   S_BT   = new((/nfl,1/),float)   do ifl = 0,nfl-1       f = addfile(fil0(ifl),"r")       f1 = addfile(fil1(ifl),"r")       S_CTL = f->SSOIL(:,0,0)       S_BT = f1->SSOIL(:,0,0)   end do ;  ListSetType (f,"cat")   print(dimsizes(fil0))   printVarSummary(S_CTL)   printVarSummary(S_BT)   nhour = 24   t=ispan(0,nhour-1,1)   m=new(nhour,float)   n=new(nhour,float) ;  p=new(nhour,float)   do i=0,nhour-1   m(i)= avg(S_CTL(i::24))   n(i)= avg(S_BT(i::24)) ;  p(i)= avg(SOBS(i::24))   end do   print(m)   print(n)     Copyright (C) 1995-2009 - All Rights Reserved  University Corporation for Atmospheric Research  NCAR Command Language Version 5.1.0  The use of this software is governed by a License Agreement.  See http://www.ncl.ucar.edu/ for more details.
