Hello,
    I was wondering how to create an expression to pull out a string from an
attribute table,  Ex: i want to pull out the word amphibian from a field
that has "amphibian,marine,birds".  Here is what i have so far:

CLASS
      NAME "progFocus"
        EXPRESSION ('[progFocus]' = 'amphibian' )
        # doesn't work when progFocus = 'amphibian,marine,bird'
      STYLE
        SYMBOL 3
        COLOR 0 0 0
        SIZE 6
        MINSIZE 1
        MAXSIZE 100
      END
    END

Would this require a regex expressions ?
thx,
Paul
