In multi-question surveys, it's sometimes convenient to quote a user's answer to an earlier question. This is called answer piping.
You can use this feature by including a word in the format of QX_ANSWER in the text of a later question. For example, when we display that question to the user, we'll replace Q1_ANSWER with the full text of that user's answer to Question 1. Similarly, Q2_ANSWER refers to the user's answer for Question 2, and so on. In the case of the survey with a screening question, Q1_ANSWER would refer to the screening answer selected.
