Arcade Expression is not working properly. Keeps showing estimated population as "N/A"

Hello, 

I am in pop up configuration, and my expression was working properly but now, it is not, instead showing N/A

below is my code: 

function safeRound(val) {
  if (IsEmpty(val)) { return null; }
  var n = Number(val);
  if (IsEmpty(n)) { return null; }
  return Round(n);
}

function ordinal(n) {
  var d = n % 100;
  if (d >= 11 && d <= 13) {
    return Text(n) + "th";
  }
  var r = n % 10;
  if (r == 1) {
    return Text(n) + "st";
  }
  if (r == 2) {
    return Text(n) + "nd";
  }
  if (r == 3) {
    return
