How to subscribe to TriggeredEvent?

The error describes the problem. The handler function signature must match what the event expects. Like so:

OnTriggeredEvent<private>(Agent: ?agent):void=

(Note that <private> is only allowed inside a class - watch indents.)
If you want to pass extra data to the handler, you can use a wrapper (similar code is available in the snippets section.)

(Listenable : listenable(?agent)).SubscribeAgentVoid(Out : tuple(?agent, t)->void, MyData : t where t:type) : cancelable =
  Wrapper := wrapper_agentvoid(t){MyData := MyData, Out := Out}
  Listenable.Subscribe(Wrapper.In)

wrapper_agentvoid(t : type) := class():
  MyData : t;
  Out : tuple(?agent, t) -> void
  In(Agent : ?agent):void = Out(Agent, MyData)

Which you could then use like this:

TriggerCancelable : cancelable = Trigger.TriggeredEvent.SubscribeAgentVoid(OnTriggeredEvent, "Your String")
