[Error] Issue with registering a partner trainer!

[Entay7777]

Hey all! Whenever I try to make a partner trainer, I am hit with this error. The trainer class is defined in the exact same manner as the supplied Brendon ally. Can anybody help me out?

Did you set up their Trainer battle?

 

[Entay7777]

Yes I have. It gets stuck on this line of code though. The battle trigger is there though.

This error happens because the trainer is not found in the database (aka the file PBS/trainers.txt, where you set the Pokémon team of a trainer). Did you define the partner trainer in the PBS file trainers.txt? If so, did you compile the game?
