[mapserver-users] understanding runtime substitution usage

[Jörg Thomsen (WhereGroup)]

Hi,

does it work without the brackets in your form?
<select name="vitigni">

because your URL is
http://localhost/cgi-bin/mapserver/mapserv.exe?map=//nbgis01/mapserver/umbe/mapfile/test10_runtimesubstitution.map&[vitigni]=Chardonnay...

and should be
http://localhost/cgi-bin/mapserver/mapserv.exe?map=//nbgis01/mapserver/umbe/mapfile/test10_runtimesubstitution.map&vitigni=Chardonnay...
