[mapserver-users] No points selected with queryByShape

Not sure I follow this.
Template is an empty layer in my map file we use to add shapes to for display.
My Feature layer is a shapefile of business point locations.
What does queryable mean in relation to a shapefile of points?

Is your feature layer queryable? That is, does is have a value set for TEMPLATE? Even ‘TEMPLATE void’ will do.

I'm baffled on this one!
I get a shape object $circle and I have a point layer $bizLayer.
I know they are both valid as they overlay as expected on my map.
When I call printBusiness to use queryByShape to get the points in the shape it always returns 0 for $numResults.
Am I missing a step somewhere?
// Get shape from point and radius
$circle = createCircle($latlonPoint,$radius);
echo 'Biz Count : ';
$bizCount = printBusiness($bizLayer,$circle);
echo $bizCount;
// Draw all the layers per basic1.map
$image=$map->draw();
// Draw circle - reads shp->draw(map,template,image);
$circle->draw($map,$emptyLayer,$image);
$image_url=$image->saveWebImage();
function printBusiness($featureLayer,$shp){
$featureLayer->queryByShape($shp);
$numResults = $featureLayer->getNumResults();
if($numResults > 0){
echo 'if';
return $numResults;
}else{
echo 'else';
return 0;
}
}
