I am trying to use itemquery to show the map centered in a polygon that
has a name (attribute data) written in a search box. As I have seen,
this can be done with an itemquery, but I just can't get this map to be
shown. I have tried something similar to Test Suite itemquery using
tutorial example, but it doesn't show (normal query map shows
correctly).

Is it something different in 4.0 version? In my template file I put:
=20
...<td><img border=3D"2"
src=3D"/cgi-bin/mapserv.exe?map=3D[map]&mode=3Ditemquery&qlayer=3Dcities_=
poly&qi
tem=3Dname&mapext=3Dshapes&value=3DFargo" height=3D"150" =
width=3D"200"></td>...
=20
- the map parameter is correctly passed to the template.=20
- cities_poly is the name of a polygon layer in the map file
- the cities shape file has an attribute called "NAME" with a string
that is the name of the city
- the city Fargo exists in the shape file
- I tried to use uppercases but nothing happened
- I tried to use itemquerymap mode instead of itemquery mode
=20
I am a little confused because somewhere there is "item", somewhere
"qitem", somewhere there is "name" somewhere "value". So what is the
right way to show a simple map centered around a polygon that has a name
written in a search box? I suppose the problem is similar to show the
street map centered around the searching street.

Thanks very much
