Activate 'Next'-Button after question is answered the first time?

You can do this using variables. I usually assign a variable to the question on the page say VARQUEST1. Then I create a Process Question button that changes the variable (VARQUEST1) to equal one once clicked. I then disinherit the Next button from the page and put a separate Next button on there that has an action that says if VARQUEST1 equals one move on, if not display a message that states the user must attempt to answer the question before they can move on. This forces them to answer the question, click the Process Question button to see if they were right or not and then they can move on. I hope that helps.

Does anybody know, how we can deactivate the 'Next-Button' until the question is answerd the first time (doesn't matter if the answer was correct or not)? We use Lectora 9. Thanks and regards, Markus
