I want to show timer in my custom mission but it is not showing. I checked OnScreenTimer option and connected ExecuteRPNAction block which contains those code:
%((C:Mission:OnScreenTimerValue) flr 60 %)%!02d!.
I got this code from here:
https://docs.flightsimulator.com/html/Additional_Information/Reverse_Polish_Notation.htm
Is this a bug or is there any other methods to show on-screen timer?
