Sequential Order for States

Hello,

I'm working on a safety module, and have four tabs (they are actually chevrons) that I want the learner to click on.  Because I want them to click on the tabs in sequential order, I have created disabled states for each of the tabs.   When the timeline starts, Tab 1 starts in normal state, but tabs 2, 3, and 4 are in disabled state.  

I have triggers set as follows: 

1. When user clicks Tab 1, change the state of Tab 1 to visited, and change the state of Tab 2 to normal.  Jump to Slide for Tab 1.  
2. When user clicks Tab 2, change the state of Tab 2 to visited, change the state of Tab 3 to normal.  Jump to slide for Tab 2.  
3. When user clicks Tab 3, change the state of Tab 3 to visited, change the state of Tab 4 to normal.  Jump to slide for Tab 3.  
4. When user clicks Tab 4, change the state of Tab 4 to visited.  Jump to slide for Tab 4.  

Everything works fine when I preview the slide (with the exception of the links to the other slides).  

However, when I preview the entire project, my tabs do not work.  

I've set the slide to automatically decide the state, and returned to saved state, and nothing works.

What am I doing wrong?  Or, am I trying to do something that can't be done with Storyline 2? 

Thanks in advance for your input!
