title: Passing information from popup form back to the original form
body: <p>This question is similar to questions that have been asked before. The solutions in the other questions have not worked for me.</p>
  
  <p>I have a form that has a dropdown list. One of the choices opens up a new form with two more dropdown lists. I need to pass the information from the form that popped up back to the original form without making a new instance of it. The information from the popup will make calculations and add new items to the dropdown list in the original form.</p>
  
  <p>I've tried using properties but I was only retrieving default values since a new instance was made. What is the correct method for passing information in this manner?</p>
