  Hey Alexander,
  
  thank you for your good work. So i’m having a dynamic form using a vlookup to show entries from another list. It’s 1 ticket with n comments. Is it possible with rules or custom code to prevent a user from saving changes until they’ve created a new note through the vlookup AddItem button?
  
  I hope you understand what I mean. Thanks

  Hello Alexander,
  
  i wasn’t able to find the link. This looks like the code I was looking for. Is there an event when vlookup is loaded succesfully so I can use the item count when opening the form and comparing the value to it when trying to save?
  
  Thanks for the fast reply.
