Resuming a course from a specific slide

Hi Heroes, 

I have stumbled upon a glitch and I cant figure out a suitable workaround.  In my course I am trying to set it so that when a user resumes the course having previously completed it, it should open on a specific slide.

I have recreated a basic version of this and attached it to this discussion.

Here is how it should work:

1. When the learner reaches the last slide of a course a T/F variable called "Complete" is set to true.

2. This then jumps to the slide I want the user to land at when they resume the course.

3.On this slide a layer shows on the condition that the 'complete' variable is equal to true.

4.When the timeline starts on the layer the T/F variable changes to False.

5. When the timeline ends on the layer a trigger will exit the course.

 

This should mean that when a learner starts a course and resumes their progress the layer should not show because the T/F variable should be False.

I had previously used this technique on another course so it should work. I have also tried similar techniques using motion paths and silent audio files but nothing seems to work.
