Hi Zachary, 

Thanks for the follow up. I would like to have the ability to update an entry ID field manually and have an updated public URL link updated with the appropriate entry ID number attached. 

Here's the JS:

(function() {
  console.log('Script loaded');

  function setupLinkForInput(input) {
    let container = document.getElementById('docLinkHolder');
    if (!container) {
      container = document.createElement('div');
      container.id = 'docLinkHolder';
      container.style.padding = '10px';
      input.insertAdjacentElement('afterend', container);
    }

    let link = container.querySelector('a.publicDocLink');
    if (!link) {
      link = document.createElement('a');
      link.className = 'publicDocLink';
      link.target = '_blank';
      link.style.color = 'blue';
      link.style.textDecoration = 'underline';
      link.style.display = 'none';
      container.appendChild(link);
    }

    function isValidDocId(val) {
      return /^\d+$/.test(val.trim());
    }

    function updateLink() {
      const val = input.value.trim();
      if (isValidDocId(val)) {
        link.href = `https://cocs-lf-1.docunavservices.com/WL-PublicWorks/laserfiche/browse.aspx?repo=Public-Works#?id=${encodeURIComponent(val)}`;
        link.style.display = 'inline';
        link.textContent = 'View Document';
        console.log( Link updated to:', link.href);
      } else {
        link.href = '#';
        link.style.display = 'none';
        link.textContent = '';
        console.log('Invalid or empty ID, link hidden');
      }
    }

    updateLink();

    input.addEventListener('input', updateLink);
    input.addEventListener('change', updateLink);
    input.addEventListener('keydown', (e) => {
      if (e.key === 'Enter') {
        e.preventDefault();
        updateLink();
      }
    });
  }

  function init() {
    let tries = 30; // 9 seconds max

    function poll() {
      const input = document.getElementById('Field93');
      if (input) {
        console.log('Field93 found by polling');
        setupLinkForInput(input);
      } else if (tries > 0) {
        tries--;
        console.log('Waiting for Field93 by polling...');
        setTimeout(poll, 300);
      } else {
        console.error('Field93 not found after polling timeout.');
      }
    }

    poll();
  }

  if (document.readyState === 'loading') {
    document.addEventListener('DOMContentLoaded', init);
  } else {
    init();
  }
})();

When I run the script manually in the console it works perfectly (see attached) but not in a live document
