[ka-Map-users] mapserver query system in kamap

Hi list,
I have a problem with the query system.
I followed the wiki page at 
http://ka-map.ominiverdi.org/wiki/index.php/Query (Using MapServer's 
Templating System for Queries).

Firstly I created the html template as specified in the wiki

  <head><title>Sample Template</title></head>
    <li> item 1 is [MY_ITEM_1]
    <li> and item 2 is [MY_ITEM_2]
    <li> but item 3 is [MY_ITEM_3]

(using only a few items... for now it is a demo...)

Then I worked on my mapfile adding the required keywords

   'queryable' 'true'
   END #metadata
   TEMPLATE '/absolute/path/to/mytemplate.html'
  END #class
 END #layer
END #map

Finally I customized the startUp.js file changing the  myQuery function 
like the following

function myQuery( eventID, queryType, coords ) {
   window.open("/cgi-bin/mapserv?map=/absolute/path/to/my/mapfile.map&mode=query&mapxy=" + coords[0] + "+" + coords[1]);

The problem, now, is that I ALWAYS get the Error

msQueryByPoint(): Search returned no results. No matching record(s) found. 

but I'm quite sure that I center the queriable element with the mouse (I 
inserted also the TOLERANCE and TOLERANCEUNIT keywords in my mapfile, 
but nothing changed)...

Can you help me guys?
It's very important for me! Please...
