[Question] Pokemon Essentials Duels?

I am trying to implement duels into my game, and I tried to use the script provided in the wiki:
Kernel.pbDuel(PBTrainers::LEADER_Surge,"Gym Leader",get_character(0),$speeches)
but it does not work, am I doing something wrong? Should I change something?

Try this:
pbTriadDuel("Lt. Surge",0,5,nil,[:PIKACHU,:RAICHU,:ELECTRODE,:ELECTABUZZ,:ZAPDOS])

There are a few example events for you to look at in the Cedolan Game Corner.

Sorry about that, I forgot there was another type of duel in Essentials.

Kernel.pbDuel(:BLACKBELT,"Dan",get_character(0),$speeches)
This is what is used on the example map on route 7, try removing "PBTrainers:"

Do you have the 12 speeches set up before the duel?
