David,

Thanks. The following is part of my .map file, which shows the extent of =
the province and the class definition:

MAP
 SHAPEPATH "../../../data"
 SIZE 300 300
 EXTENT 145000 6688000 885000 5400000
...
WEB
  TEMPLATE alberta.html
END

 LAYER
  NAME alberta
  DATA alberta_10tm
  STATUS default
  TYPE POLYGON
   CLASS
     OUTLINECOLOR 212 212 212
     COLOR 0 0 0
     TEMPLATE 'case1_template.html'
   END
 END
...

This is the form part of the HTML template:
-------
<input type=3D"hidden" name=3D"mode" value=3D"itemquery">
<input type=3D"hidden" name=3D"qitem" value=3D"ID">
<input type=3D"hidden" name=3D"qlayer" value=3D"alberta">

<select name=3D"qstring" size=3D"1">
<option value=3D300>300</option>
...=20
-------

The URL request (simplified) after submitting the form is as follows:
http://24.79.12.230/scripts/mapserv.exe?mapserv=3D...mapserv.exe&map=3D..=
.alberta.map&map_web_imagepath=3D...queries&map_web_imageurl=3D...queries=
&mode=3Ditemquery&qitem=3DID&qlayer=3Dalberta&qstring=3D300

I'd appreciate it if anyone can see anything wrong with this picture.

Chris
