[MapServer-users] using SCALETOKEN in an EXPRESSION

[Richard Greenwood]

Can anyone tell me what's wrong with my EXPRESSION below? I'm trying to
filter features from the National Hydrology Dataset based on scale
using SCALETOKEN and I can't seem to get it right. [Visibility] is a field
in the data that suggests the scale at which a feature should be shown.

Thanks!

LAYER
  NAME "flowline"
  TYPE line
  DATA "shapefiles3857/nhd/flowline"
  SCALETOKEN
    NAME "%priority%"
    VALUES
      "0"       "0"
      "24000"   "24000"
      "50000"   "50000"
      "100000"  "100000"
      "250000"  "250000"
      "500000"  "500000"
      "1000000" "1000000"
      "2000000" "2000000"
      "5000000" "5000000"
    END
  END
  CLASS
    EXPRESSION ([Visibility] > %priority%)
    STYLE
      COLOR 158 196 255
      MINSIZE 1
      SIZE 3
      MAXSIZE 6
    END
  END
END
