Restricted navigation 1st viewing, free navigation on the second?
Apologies for the Subject title - couldn't work out how to best phrase it!
I have a story that won't be hosted in a LMS, it has 9 buttons which lead to different sections. On the first viewing, the buttons are locked so the learner has to view the sections in a certain order. Once a section is viewed, the variable is changed to true and the next section is unlocked. The problem is we also want it to be used as a reference tool, so the 2nd, 3rd, 4th time they view the eLearning the navigation isn't restricted.
Any help would be greatly appreciated - even if it's certain 'No, this can't be done!'
