Hello @neelamallik,

The mistake is that g_form.isFieldChanged() does not exist in ServiceNow client scripts, so your code errors out. You can achieve the same behavior by checking the .changed property of the field controls instead. 

// Check if the fields have been modified since the form loaded 
var groupChanged = g_form.getControl('assignment_group').changed; 
var assignedChanged = g_form.getControl('assigned_to').changed; 
var comments = g_form.getValue('work_notes'); 
 
if ((groupChanged || assignedChanged) && !comments) { 
   alert('Please enter work notes when reassigning the ticket.'); 
   return false; 
} 
 return true;

 If my response helped, please mark it as the accepted solution so others can benefit as well.
