Increment / decrement a counter based on states

When an object has multiple states, I suggest you avoid triggers with conditions that check if the object = Normal, because all of the states have a bit of Normal in them. 

The easiest fix in this case is to use an "Else" statement in the trigger. For example: 

This is demonstrated in the attached file.

Another option would be to use "≠ Selected" (instead of "= Normal").
