Here’s a helpful and relevant reply you can use for that thread:

It looks like you’re on the right track with your script, but there are a couple of possible issues that could cause the calculator to not work within the Calculated Fields Form plugin:

1. Smart Quotes: The code you posted uses curly quotes (‘fieldname3’), which are not valid in JavaScript. Make sure you replace them with straight quotes: 'fieldname3'.
2. Field Format: Ensure that the date input format in your fieldname3 is consistently MM/DD/YYYY, as your script depends on this structure.
3. Logic Order: You’re checking younger divisions first (e.g., U12), but that could misclassify someone born in 2009 as U12. You should check older divisions first, then move toward younger ones.

Here’s a corrected and improved version of your script:

(function() {
  var dobStr = field('fieldname3'); // Your DOB field name
  if (!dobStr) return '';

  // Parse MM/DD/YYYY format
  var parts = dobStr.split('/');
  if (parts.length !== 3) return 'Invalid date format';

  var month = parseInt(parts[0], 10) - 1;  // JS months zero-based
  var day = parseInt(parts[1], 10);
  var year = parseInt(parts[2], 10);

  var dobDate = new Date(year, month, day);
  if (isNaN(dobDate.getTime())) return 'Invalid date';

  // Cutoff dates (June 30 each year)
  var cutoff_U16 = new Date(2009, 5, 30);
  var cutoff_U15 = new Date(2010, 5, 30);
  var cutoff_U14 = new Date(2011, 5, 30);
  var cutoff_U13 = new Date(2012, 5, 30);
  var cutoff_U12 = new Date(2013, 5, 30);

  // Check from oldest to youngest
  if (dobDate <= cutoff_U16) return 'U16';
  if (dobDate <= cutoff_U15) return 'U15';
  if (dobDate <= cutoff_U14) return 'U14';
  if (dobDate <= cutoff_U13) return 'U13';
  if (dobDate <= cutoff_U12) return 'U12';

  return 'Not eligible';
})();

Also, if you’re working with age-related logic in forms or need more advanced age calculations — like calculating age down to the minute — you might find this helpful tool:
👉 حساب العمر بالدقائق — an Arabic calculator that can compute age in detail.

Let me know if you need help integrating this into your specific form setup!
