Issue with subscripts in array

Hi

I am using the following script:

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"

begin
a=addfile("geo_em_flatasia.d01.nc","w")
topo = a->HGT_M
printMinMax(topo,True)
print (dimsizes(topo))

do i=0,89,1
 do j=0,99,1
  if (topo(0,i,j).gt.200) then
   topo(0,i,j) = (200 + (0.01*(topo(0,i,j)-200)))
  end if
 end do
end do
printMinMax(topo,True)
printMinMax(a->HGT_M,True)

end

​I am getting the following output:
