legend, newbies question.

[An Tay Nguy]

Hi everyone,

I am trying to create a legend for a shapefile.  The legend is created
correctly if my layer definition is:

LAYER
  NAME dnnetano_10tm.shp
  TYPE PolyLine
  STATUS on
  DATA 'd:/geodata/1_2million/alberta/dnnetano_10tm'

      CLASS
        Name 'Dnnetano_10tm.shp'
        COLOR 240 118 178
        OUTLINECOLOR 0 0 0
     END  # CLASS

END  # LAYER

If I define my layer definition like the one below, I get a blank legend.
Does anyone knows what I did wrong?  I would've expected 12 entries in the 
legend.  

LAYER
  NAME alpparkg_10tm.shp
  TYPE Polygon

END  # LAYER

Thanks in advance for your help.
