Search and Rescue error

[SunlitZelkova]

I was using the Downed Pilot and SAR script (from either apache85 or angster, I am sorry, I don't remember who made it!), and I tried to use it in another scenario. It works for one time on one side, but after that does not work.

I am getting an error like this-

Lua script execution error: [string "Create Pilot"]:1: attempt to call global 'CreatePilotFromTriggerUnit' (a nil value)

The scenario is attached, the error is shown right after loading it.
