Nice work Thomas! That's got it.
http://localhost/cgi-bin/mapserv?map=/media/D_Drive/www/gis/business.map&layers=business_rd4%20states&mode=map
Now I can call any of the 4 from one .map file.
Now I just need to figure out how to call a specific layer via a .php file.
Thanks a lot, very subtle change there Adding STYLE in front of SYMBOL.
