MessageYes, you can use all sorts of logical expressions in parenthesis.
eg.:
CLASS
EXPRESSION ([CODE]=15 and '[CNTY]'='MyCounty')
In this case, you need not set CLASSITEM in LAYER definition (but if set, it
is not used).
(Be sure if the string expressions are quoted.)

Pøedmìt: [Mapserver-users] Classification on more than 1 classitem
Hi all,
I know there have been questions about this before, but I could not
actually find a definitive answer. I need to perform a classification based
on a condition using two attributes. Is there a way to have two classitems?
Regards,
Jacob
