[mapserver-users] Variable-substitution cause WMS GetFeatureInfo error

[AlessioDL]

I post the my code... hope this "helps to help" :-)

Mapfile layer:

          LAYER
                NAME 			"QueryAreas"
		TYPE 			POLYGON
		CONNECTIONTYPE 	postgis
		CONNECTION		"host=localhost user=***password=*** dbname=***"
		DATA			"the_geom FROM (SELECT * FROM areas)AS foo USING UNIQUE gid USING
SRID=4326"
		FILTER 			"YEAR = %YEAR%"
		METADATA
			"wms_title" 					"Query Areas"
			"wms_include_items" 			"all"
			"wms_exclude_items"			"the_geom"
		END
		DUMP TRUE
		STATUS ON
		TRANSPARENCY ALPHA
		CLASS
			TEMPLATE 		"../TemplateMS/areas.html"
			NAME "Areas"
			STYLE
				SYMBOL 		 "simpleline"
				SIZE		 2
				OUTLINECOLOR 0 0 0
				COLOR		 255 127 36
			END #Style end
		END #Class end
	END #Layer end

OpenLayers code:
