Both your questions are solved the same way. You must check the question for correctness yourself rather than letting Lectora do it when it advances to the next page. Put a button on the page (or replace the next button) that evaluates the question (Condition tab in an action allows you to check the question variable for correct or not correct.) If correct, go to next page. If not correct, run an action group that provides the necessary feedback and anything else you want to do.If this is not clear, please post questions.
