on an explanation he told me some weeks ago... I tried with this but it
doesn't work for me.
I have one layer with some class on it and  ALL are done. Where have I the
error???

.map:

	LAYER # Provincias polygon layer begins here
		NAME		provPerimeter
		DATA        provin
		STATUS      OFF
		TYPE        POLYGON
		GROUP		Provincias
		
		PROJECTION
		  "init=epsg:23030"
		END

		METADATA
			"title" "Provincias"
		END	
		
	     LABELITEM "Divi"
	     CLASSITEM    "Case1"
			CLASS
				EXPRESSION "D1"

			END
			CLASS

Same idea, but you have to know the range of colors that are possible 
and create a CLASS for each COLOR then use an EXPRESSION to select the 
color instead of the "divi" so if your values were like 1 .. 100 and you 
wanted assign colors based on 1-10, 11-20, 21-30, ..., 91-100

CLASS
   EXPRESSION ([divi] < 11)
   STYLE
     COLOR ...
   END
END
CLASS
   EXPRESSION ([divi] < 21)
   STYLE
     COLOR ...
   END
END
...
CLASS
   # no expression is like an default: and will catch
   # anything not caught above.
   STYLE
     COLOR ...
   END
END

CLASS is like a CASE statement, it will stop after one is selected.
