Conditional Trigger Help - Combination of AND/OR triggers

I have 4 checkboxes and 4 slide layers.  I'd like to display a slide layer based on how the boxes are checked, as follows:

  1. Complete Layer (boxes 1/3/4 checked, box 2 unchecked)
  2. Incomplete Layer (boxes 1/3/4 unchecked, box 2 checked)
  3. Partially Complete Layer (box 2 unchecked, any combination of boxes 1/3/4 checked (but not all))
  4. Partially Incomplete Layer (box 2 checked, along with any other box)

Items 1 and 2 are working as intentded using AND triggers.  Items 3 and 4 are not working for me.  I've tried using a combination of AND and OR statements, but am not having any luck. 

Thoughts?
