title: Gravityforms field value from another field
body: <p>I'm trying to make a field with Gravity Forms that gets its value(s) from other fields in the same form. Is this possible with merge tags for example?</p>
  
  <p>Reason for this is I'm trying to get a simple list of values from multiple fields that I can store in user_meta (with GF user registration). There are 10+ checkbox fields, where the user can select 1 or all. This new field would serve as a hidden field that gets all the data user has entered (checked) in the checkbox fields. GF user registration accepts only one field as a pointer for the user_meta value so making the logic in that end is a no-go.</p>
