Help with code

I try to check if this reference field is null (has no values to choose from) - not only empty.

Hi @B_pppppp ,

Could you try below code 

function onLoad() {
  // Get a reference to the business_service control
  var fieldObj = g_form.getControl('business_service');

  // Check if control exists and there's more than one option
  if (fieldObj && fieldObj.options.length != 1) {
    // Set business_service field to mandatory
    g_form.setMandatory('business_service', true);
    
  }
}

@B_pppppp Please try with below 

function onLoad() {
  // Get a reference to the business_service field
  var fieldObj = g_form.getControl('business_service');

  // Check if control exists and if the field is empty
  if (fieldObj && g_form.getValue('business_service') == '') {
    // Set business_service field to mandatory
    g_form.setMandatory('business_service', true);
  }
}

@Maddysunil , thank you! It works a little too well now: it makes the field mandatory even if I can't choose any value for it because there's none
