Color Bar

Dear NCL users,
I am having difficulties trying to arrange the color bar on the
following plot. I want the plot to look like the test.Auto_levels.png
figure (see attachment), however I want to adjust the bar to start
from 0 to 100. When I set the cnLevelSlectionMode to Manual level and
select the contour spacing I get the test.Manual_levels.png (see
attachment) figure and for some reason the colors change. This is what
I have as my settings (see attach). I think I am missing something,
but I can not figure out what seems to be the problem if it is on the
label bar or with the colors. Not sure. Let me know if you have any
suggestions. Thanks.

res = True ; plot mods desired
; Contour lines settings
  res@cnFillOn = True ; turn on color
  res@cnLinesOn = False ; no contour lines

  res@cnLevelSelectionMode = "ManualLevels" ; set manual
contour levels
  res@cnMinLevelValF = 0. ; set min contour
level
  res@cnMaxLevelValF = 100. ; set max
contour level
  res@cnLevelSpacingF = 10. ; contour spacing

  res@gsnSpreadColors = True ; use full color
map
  res@gsnSpreadColorStart = 0
  res@gsnSpreadColorEnd = -2 ; don't use added
gray
  res@lbOrientation ="vertical" ; vertical label
bar
  res@lbLabelAutoStride = True ; every
other label

; Map settings
  ;This will start Zooming into the MAB and creating a Mercator
Projection

res@mpProjection = "mercator" ; projection
  res@mpLimitMode = "Corners" ; method to zoom
  res@mpLeftCornerLatF = minLat;min(lat)
  res@mpLeftCornerLonF = minLon;min(lon)
  res@mpRightCornerLatF = maxLat;max(lat)
  res@mpRightCornerLonF = maxLon;max(lon)

  res@cnFillDrawOrder = "PreDraw" ; fill first

  res@gsnAddCyclic = False;
  res@mpLandFillColor = "gray"; Map fill color is gray
  res@mpOutlineOn = True; Draw map outline
  res@mpDataBaseVersion = "HighRes"; Medium resolution map

  res@mpDataBaseVersion = "HighRes" ; use MAB High
Resolution
  res@pmTickMarkDisplayMode = "Always" ; turn on tickmarks
  res@mpFillDrawOrder = "Draw"

; Turn on map grid
res@mpGridAndLimbOn = True;
; Set gridline intervals
res@mpGridSpacingF = 0.5; ; 1/2 degree intervals
res@mpGridLineDashPattern = 2; ; dashed line
res@mpGridLineThicknessF = 0.5;
