[PBS Question] NPC VS NPC error

I am trying to put the scrip of this link: (broken link removed)
When I tried it, I got an error. I am working on version 16

Error
---------------------------
Script 'Interpreter' line 276: RuntimeError occurred.

Script error within event 43, map 110 (Mapa de pruebas):

Exception: TypeError

Message: Section050:1169:in `text_size'cannot convert Array into String

***Full script:

Don't you need to give a losing speech for trainer1? (I don't know if that's what your error is, my guess is that v16 is different from v17, which is what RC says this script is for)

It did not work to add the defeat phrase, maybe the version 17.2 script is incompatible with the version I use that is 16.

Thanks for replying equally
