In that case this should work:


    VALIDATION

      'county'  '^[0-9]{1,2}$'

    END



    This limits county to a 1 or 2 digit number.



    Note you'll get better performance using a plain string expression, e.g.:

    CLASSITEM 'county'

    CLASS

      EXPRESSION '%county%'

      ...

    END

Dear anyone willing to help,

I'm having a hard time interpreting how to properly execute runtime cgi variable substitution using an <input> of type=text.

If I replace '%county%' with a sample county attribute value in single quotes the EXPRESSION works and is displayed on the returned html template.

Currently my html input variable in the template looks like this  :
<input type="text" id="county" name="county"  />

...and my mapfile variable to be substituted for looks like this:
                LAYER
                                NAME blah_ohio
                                STATUS OFF
                                TYPE POINT
                                DATA BLAH/BLAH_Ohio
                                PROJECTION
                                                "init=epsg:3754"
                                END
                                CLASS
                                                NAME 'Class1'
                                                EXPRESSION ('[County]' eq '%county%')
                                                STYLE

                                                                SYMBOL "circle"
                                                                COLOR 250 50 50
                                                                OUTLINECOLOR 0 0 0
                                                                SIZE 2
                                                END
                                END
                                METADATA

                                                "wms_title" "blah_ohio"
                                                "wms_srs" "epsg:4326"
                                END
                END

Thanks in advance,
Paul
