I am calculating the % POE by array(
            "label"=>"% a POE",
            "type"=>"integer",
            "value"=>function($row) {
                if (($row["research_dol"]+$row["support_dol"]+$row["supervision_dol"])==0)
                     return 0;
                else
                    return($row["research_dol"]*100/($row["research_dol"]+$row["support_dol"]+$row["supervision_dol"]));
            },
What kind of type will get just a whole number?
