[ms4w-users] problems querying shape via mapscript

Do you have a template line in your mapfile? Something like below? You
don't need to actually reference a real template, but just put in the
name of a null html file, (from what I understand).
It makes the layer queryable.
Template file or URL to use in presenting query results to the user.

Subject: [ms4w-users] problems querying shape via mapscript
I'm having a problem with querying a shapefile layer, using
"queryByPoint", basing my prototype on gmap demo application. Everything
works fine, it shows me all the layer present in the map, the coordinate
points "$nClickGeoX,$nClickGeoY" are correctly transformed from screen
coords to projected coords, but "$numResults " is always equal to 0...
I'm going mad! What's wrong with my script? Do I have to set some
particular tags in teh mapfile to allow querying? (In the map demo there
isn't any particular tag).
Help, it's urgent...
$oClickGeo = ms_newPointObj();
@$gpoMap->queryByPoint($oClickGeo, MS_SINGLE, -1);
for($iLayer=0; $iLayer < $gpoMap->numlayers; $iLayer++)
$oLayer = $gpoMap->GetLayer($iLayer);
$numResults = $oLayer->getNumResults();
