Tabs interaction with guided tab interaction

Hi there,

 

I'm using Storyline 360 and I've built a Tab interaction menu following the tutorial of Thor Melicher.

I've set all the correct triggers and layers and I'm very excited about the software.

Only one problem...

The tabs should initially have interaction in a certain order to increase the learning curve.

After a certain tab has been visited, I'm fine with learners clicking back and forth. 

I've created a Scene with 1 slide. Base layer that has the buttons, then layers per tab that have a text box with the tab info on it. 8 layers total.

Order should be:

Arrive at base layer - tab 1 - tab 2 - tab 3 - tab 4 - tab 5 - tab 6 - tab 7 

with possibility to revisit previous tabs.
