In surveys having multiple questions its sometimes needed to re-use or quote respondent's answers to a previous answered questions or answers. This process is called piping. ngSurvey supports two types of piping

  • Text / Data piping to pipe the respondent answers as plain text into labels or survey content.

  • Carry Forward / Carry on Answers to pipe the actual respondent answers into another question and allow these answers to be selected again from that new question. Carry forward answers are usually used with multiple selection questions where you first want to ask the respondent to choose among a set of multiple answers and then ask a more specific question about only the answers that have been selected in the multiple selection question.
