Table of Contents - prevent navigation if Module not completed

Hi there,

I have multiple Scenes within a Story. The scenes A, B, C, and D are meant to be taken sequentially and in the Player menu, I have set the pages to 'Restricted' so that a learner cannot proceed through without completing the pages prior.

However, at the beginning of the Story I have a 'Table of Contents' page where learners can click an object to go directly to scenes A, B, C, and D. The problem is - this seems to be a 'work around' for the Learner to do the scenes out of order (i.e. if you click the object for Scene B, the Learner can go to Scene B without having completed Scene A). I'd like to have this set up so that if the Learner clicks a Scene for which they haven't completed yet, I can stop prevent them from going to it. 

I am trying to play around with the Triggers and Conditions but haven't had any success preventing this from happening. Does anyone have any guidance on how to address this? Thank you!
