var hideStuff = function() {
  if (#{@platform.platform_type == 'rewards'}) {
    var row = document.getElementsByTagName("tr");

    for (var i = 0; i < row.length; i++) {
     if (row[i].innerHTML.search("Accreditation") != -1) {
       row[i].style.display = "none";
     } else if (row[i].innerHTML.search("Escrow") != -1) {
       row[i].style.display = "none";
     }
    }
  }
}

hideStuff();
