[addaction without external script]

Here's a solution I've been working on just this past week, after only having just discovered the AddAction command is broken!
The toggle is based upon your assistance and code above. So thanks to "raymix" above for your persistence. I'm only 5 years late and god knows how many hours I've persisted this week. Easily close to 8+ hrs studying and learning code. 

Below I've now updated my post which demonstrates three versions of using "addAction" command to toggle your captive state.
This includes _StringSelect != _toggle_NotEqualOn ; _StringSelect == _toggle_EqualOn ;  Case with switch (_StringSelect) do {} , examples: 

Initialization code included for player, enjoy!
