title: Populating subform fields from main form field
body: <p>I'm building a multi-page form with subforms for a number of tables. The form is to collect very detailed information about patients, and the patientID is included in several tables.</p>
  
  <p>Can the patient ID input from the main form(master table) populate a hidden field with the same patient ID in subsequent subforms?</p>
  
  <p>Thanks for any assistance.</p>
