Developing Test Questions

We're using Lectora Professional Publishing Suite. We came across an issue in developing the test section of our first module.Issue #1:If the answer is incorrect, we set up a function that displays a pop-up message that says, "That is incorrect." However, when you hit the 'Ok' button it takes you to the next page instead of keeping you on the same page for another chance at selecting the right answer. Would anyone know how to keep the user from proceeding to the next slide until the correct answer is selected in Lectora? Issue #2:If the answer is incorrect, we can setup a function that sends the user back to the page that the answer is located for review. However, when you set a feedback window to appear the pop-up message that says, "That is incorrect" does not display. Would anyone know why this happens and how that can be fixed as well?Please let us know if anyone could help us out. Thanks, we appreciate the help!
