Try using uppercase characters in the expression:

EXPRESSION ([SIG_NBR] < 6)

  Hi all,

  I'm using Mapserver version 3.4 and have some problems with the
expressions in the classes.
  In my ShapeFile the column is defined as integer, but mapsever doesn't
recognize it as integer. When I switch to EXPRESSION 1/2/3/4/5/ it works.
(it seems that mapserver only recoginzes the column as strings).
Unfortunately I need the integer values.

  here is the part of my mapfile

  LAYER
    NAME hausnr_na
    DESCRIPTION "gekündigte Wohnungen"
    TYPE POINT
    STATUS ON
    CLASSITEM 'Sig_nbr'
    DATA nichtar4
        CLASS
          NAME "1"
          #EXPRESSION /1|2|3|4|5/     # works
          EXPRESSION ([sig_nbr] < 6)     #works not
    SIZE 8
   SYMBOL 2
    COLOR 255 250 250
  END
  END

  cheers,
  gernot
