Thanks for your help J.D.!! This project is for a client that was pretty adamant that the solution be as low or no code as possible. I can hide/collapse the text box so I should be able to control it.
Not sure if I can make the text box a child of the multi-select box field so that when the multi-select box appears the text block does as well or, if I need to do it by using expand() and collapse() or, if another/better solution is the way to go.
Ideally I’m looking for a solution the client can easily replicate in the future with other questionnaires…
