I hope that you guys could help me with the following problem:
I have made a page that displays a book (data extracted from Google books API) and the page also displays sellers of this book in a repeating group if there is one in the database. When there is a seller in the database this works fine. However, I want to hide the repeating group when there are no sellers and display text e.g. “Unfortunately nobody sells this book yet.” I can’t fix this and have tried many things e.g. the “when is empty” option and "doesn’t contain"option.
