Overview

Values from a subform submission can be automatically inserted into a main form using Answer Piping. By referencing subform responses, you can populate any field where answer piping is supported, such as question fields, headings, default values, labels, logic, and more. This speeds up form completion and reduces data entry errors. For example, you can:
  • Auto-fill contact information collected in a subform into the main form
  • Reference prior selections to personalize questions or instructions
  • Carry over calculated values or totals from a subform into summary fields in the main form
