only ONE class is drawn for each feature, the first one in the rder of
the mapfile to meet the expression and scale tests. so your second
class is never rendered in this case.

CLASS
     NAME "Rightand left"
     EXPRESSION /^FO040314$/
     STYLE
         SYMBOL right
         SIZE 24
         COLOR 51 102 0
     END
     STYLE
         SYMBOL left
         SIZE 24
         COLOR 102 51 0
     END
END


cheers,
thomas
