Displaying classes in a layer

[Wouter Schaubroeck]

Hi all,

I'm just learning how to work with mapserver. I do this by following the
tutorial on http://terrasip.gis.umn.edu/projects/tutorial/.
But i'm stuck at example 1.3. My mapserver is configured correctly (I
think, because the two first are displayed correctly), and the mapfile
is also ok. But it doesn't work!!! What do I wrong?
This is the mapfile:

MAP
 IMAGETYPE      PNG
 EXTENT         201621.496941 -294488.285333 1425518.020722 498254.511514
 SIZE           400 300
 SHAPEPATH      "data"
 IMAGECOLOR     255 255 255

 PROJECTION
   "proj=laea"
   "ellps=clrk66"
   "lat_0=45"
   "lon_0=-100"
   #
   # Alternatively, you can specify an EPSG code.
   # "init=epsg:2163"
   #
 END

 # Start of LAYER DEFINITIONS ---------------------------------------------
 LAYER # States polygon layer begins here
   NAME states_poly
   DATA states_ugl
   STATUS DEFAULT
   TYPE POLYGON

   PROJECTION
     "init=epsg:4269"
   END

   CLASSITEM "CLASS"
   CLASS
     EXPRESSION 'land'
     COLOR 232 232 232
   END
   CLASS
     EXPRESSION 'water'
     COLOR 198 198 255
   END
 END # States polygon layer ends here

 LAYER # States line layer begins here
   NAME states_line
   DATA states_ugl
   STATUS DEFAULT
   TYPE LINE

   PROJECTION
     "init=epsg:4269"
   END
     CLASSITEM "CLASS"
   CLASS
     EXPRESSION 'land'
     COLOR 32 32 32
   END
 END # States line layer ends here
 # End of LAYER DEFINITIONS -------------------------------
END # end of map file

Thx in advance!!!
