[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 [filename] 
Template file or URL to use in presenting query results to the user.


NAME "World Boundaries"




TEMPLATE ttt.html

	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();
	    $oClickGeo->setXY($nClickGeoX, $nClickGeoY);
	    @$gpoMap->queryByPoint($oClickGeo, MS_SINGLE, -1);
	    for($iLayer=0; $iLayer < $gpoMap->numlayers; $iLayer++)
	    $oLayer = $gpoMap->GetLayer($iLayer);
	    $numResults = $oLayer->getNumResults();
	    echo $numResults;
