Cloaking Pages

If I'm understanding what you're asking in your first question, all you need to do is to put these pages in a separate chapter (I usually call mine "Nonlinear Pages") and, at the chapter level, deselect the "Include in Table of Contents" checkbox. As for your second challenge, if you're saying that you want a nav menu on the left but want to prevent some of the chapters from being accessible until others have been visited, you'll probably need to create a manual version of the nav menu, with invisible buttons on each of the chapter names that test for a particular variable value before letting the user access that chapter/page. That variable value would be changed when the user accesses the prerequisite chapters and you'd be testing to see that the variable value has changed appropriately before enabling the "go to next page" action and displaying a message to the user if the variable value indicated that they had not yet seen the prerequisite info.Hope this helps!Laura
