Sometimes, we have to set some field to required to make sure we don't allow our end users to accidently miss answering a question.  A required field will ensure the end user answers the question before they are allowed to submit the form.  


To set any field to required.  Simply...

  1. Drag the field over to the form and place it where you would like.  
  2. Click on the "Validation" tab.
  3. Click the "Required" checkbox


That's it!
