"Multiple Tries" Question

Wally, I have helped a lot of people out on this forum and your question is typical but would take a long time to answer. It is not trivial. To start with, take a look at my FREE Lectora Coding Tips which should give you some background on how to do this. If this is not enough, you could look at my earlier book, Lectora 301 - Interesting Courses Using Variables & More which has worked examples of what you are looking to do. It does not follow the later Lectora Coding Tips - it uses another technique.
