Can anyone tell me if what I am attempting is possible, and perhaps share
with me the required syntax?

I am attempting to use the CGI version of mapserver to create a map
highlighting one or more counties (or townships, cities...) based upon a
dynamically generated URL.  I am able to highlight single counties with this
syntax:

http://www.mba.state.mn.us/cgi-bin/mapserv?map=/home/httpd/html-MBA/maps/cou
nty.map
<http://www.mba.state.mn.us/cgi-bin/mapserv?map=/home/httpd/html-MBA/maps/co
unty.map&map_county_class_expression(NAME_LOWER=Hennepin)&mode=map>
&map_county_class_expression(NAME_LOWER=Hennepin)&mode=map

Changing the county name changes what is mapped. How, however, do I make it
do multiple counties? I have tried lots of variants of the syntax suggested
in the documentation
(http://mapserver.gis.umn.edu/doc36/mapfile-reference.html#class
<http://mapserver.gis.umn.edu/doc36/mapfile-reference.html#class> ) such as:

http://www.mba.state.mn.us/cgi-bin/mapserv?map=/home/httpd/html-MBA/maps/cou
nty.map&map_county_class_expression(NAME_LOWER='Lake'
or[NAME_LOWER]='hennepin')&mode=map

Many thanks for any assistance.

Cheers,
