Hi, I have challenge with getting this query to execute. I followed your examples but not sure if there is any way to see what is coming out. Glad for some assistance in resolving it.
The query
class PaymentList extends KoolReport
{
use \koolreport\inputs\POSTBinding;
use \koolreport\export\Exportable;
	
  protected function defaultParamValues()
    {
        return array(
            "academic_year_id"=>array(),      "term_id"=>array(),		"payment_call_id"=>array(),			"community_id"=>array()
        );
    }
    protected function bindParamsToInputs()
    {
        return array(
			"academic_year_id",	"term_id",		"payment_call_id",	"community_id",
        );
    }
    public function settings()
    {
        $config = include "../config.php";
        return array(
            "dataSources"=>array(
                "abc"=>$config["postdb"]
            ),
        );
    }   
	
    protected function setup()
