preventing fast tracking through a storyline training module

Hi there,

We have created a Storyline training module which includes buttons that play media and a try video where the learner must interact with the content before they are considered trained.  When we preview our training module we are able to fast track through the content without viewing every slide.  We are pretty sure the when our staff find out they can do this and skip slides they will do so.  How do we set up our training module to ensure that every slide is visited and prevent learners from skipping through the module to the last slide without viewing and completing the required work in the try video slides?

Thanks,

Kirsten
