use (/ .. /) if this is not the desired result

I am always messing up this sort of thing in NCL. The error messages
below are totally cryptic to me. Do you have any general comments about
what these things mean? Any help would be appreciated.
These are warning messages, and the output netcdf file I want actually
does get written. But what???

Code snippets:
;Make a bunch of netcdf variables for output
var_names3D = (/"tide_Ephase","tide_Eamp","tide_Cphase",\
                "tide_Cangle","tide_Cmin","tide_Cmax"/)
var_types3D = (/ "double", "double", "double", "double", "double",
"double" /)
filevardef( out, var_names3D, var_types3D, \
         (/ "tide_period", "eta_rho", "xi_rho" /) )

; Make a scratch array and zero it out
grd=out->tide_Ephase
grd=0.0

; Fill the scratch array and write it back out to pre-defined variable
; Cangle
print("Cangle")
nodevalues=intide->tide_Cangle
print("After nodevalues=")
do iperiod = 0,tide_period-1
  kperiod = periodpointer(iperiod)
  Fperiod = tidefacpointer(iperiod)
   do k = 0,node-1
     grd(iperiod,i_rho(k),j_rho(k))=nodevalues(k,kperiod)
  end do
end do
print("before out->")
out->tide_Cangle=grd

; Cmin
print("Cmin")

The output:::::::

(0) Cangle
(0) After nodevalues=
