Page skipping prevention

Hello all,

currently I have a course with a menu on the left hand side of the course. Now each section can be clicked and accessed with the go to -> Page -> and page they want to access.

What type of control(s) can I create to force a user to have to go through a preset (by me) Linear order?

for example. you can go to page 1. Once you are done, you can go to page 2. Now you cannot go to page 4 without viewing page 3. etc.

Any insight to this will be extremely helpful. I am quite new to Lectora and would love to learn these types of variables / actions.

Thank you.
