Last Slide Dilemma

I have completed my first eLarning course for a company and getting ready to submit the SCORM version to their LMS team.

I have only one problem left to fix (Phew!).

I need to make it so the learners cannot access the last slide through the slide titles. I need to makes it so the an official completed course ONLY happens when they have viewed all the previous slides.  The final slide is marked so to speak as being the completed course.

I know I have seen this somewhere but as neophyte I don't even know what to search under.

Thanks for your help, team.
