Here is a not very elegant solution. Create a hidden button (or text block with one action) for EACH question on the last page. Link each button (or text block's action) to its question with GoTo Chapter/Section/Page.On each question page, have a button to flag the question by adding a text a unique 2 character string to a variable 1a, 1b, 1c, 1d, ... 2a, 2b, ...On the last page where the buttons are, you will need one action for text block that shows the block if the variable contains the string it is associated with. This is a LOT of work. Hopefully someone else can come up with a better solution.
