Add new symbol in symbols.sym

[Jonathan]

Dear all,

I added a new symbol in the symbols.sym please see code below.

Symbol
Type PIXMAP
IMAGE 'view1.gif'
Name 'viewpoint1'
Transparent 3
END
END

however when I used it for a layer, this error came up: *Warning*:
[MapServer Error]: msLoadMap(): Undefined overlay symbol "viewpoint" in
class 1, style 0 of layer ViewPoints.

the layer in the map file is defined as:

LAYER
  NAME ViewPoints # name of the layer
  METADATA
    "DESCRIPTION" "View Points"
  END
  TYPE point # feature type
  STATUS ON
  DATA viewpoints
  CLASSITEM "viewAngle"
  CLASS
      EXPRESSION "0"
      SYMBOL viewpoint0
    SIZE 8
  END
  CLASS
      EXPRESSION "1"
      SYMBOL viewpoint1
    SIZE 15
    TEMPLATE "ttt_query.html"
     NAME "viewangle1"
     COLOR 255 0 0
  END
  CLASS
      EXPRESSION "2"
      SYMBOL viewpoint2
    SIZE 8
  END
  TOLERANCE 5
END


Any idea why this is happenning?
regards
