[Scripting Question] Changing how Multitype works

[Arkadious]

Hello everyone, just a quick problem I was hoping someone would be able to please help me fix. I'm trying to change Multitype to work that it changes Arceus's type also when it is holding a Z-Crystal like in the Generation VII games.

Currently I've got the code for Multitype set up in Pokemon_Forms like this:

MultipleForms.register(:ARCEUS,{
"getForm"=>proc{|pokemon|
   next 1  if isConst?(pokemon.item,PBItems,:FISTPLATE,:FIGHTINIUMZ)
   next 2  if isConst?(pokemon.item,PBItems,:SKYPLATE,:FLYINIUMZ)
   next 3  if isConst?(pokemon.item,PBItems,:TOXICPLATE,:POISONIUMZ)
   next 4  if isConst?(pokemon.item,PBItems,:EARTHPLATE,:GROUNDIUMZ)
   next 5  if isConst?(pokemon.item,PBItems,:STONEPLATE,:ROCKIUMZ)
   next 6  if isConst?(pokemon.item,PBItems,:INSECTPLATE,:BUGINIUMZ)
   next 7  if isConst?(pokemon.item,PBItems,:SPOOKYPLATE,:GHOSTIUMZ)
   next 8  if isConst?(pokemon.item,PBItems,:IRONPLATE,IRONIUMZ)
   next 10 if isConst?(pokemon.item,PBItems,:FLAMEPLATE,FIRIUMZ)
   next 11 if isConst?(pokemon.item,PBItems,:SPLASHPLATE,:WATERIUMZ)
   next 12 if isConst?(pokemon.item,PBItems,:MEADOWPLATE,:GRASSIUMZ)
   next 13 if isConst?(pokemon.item,PBItems,:ZAPPLATE,:ELECTRIUMZ)
   next 14 if isConst?(pokemon.item,PBItems,:MINDPLATE,:PSYCHIUMZ)
   next 15 if isConst?(pokemon.item,PBItems,:ICICLEPLATE,:ICIUMZ)
   next 16 if isConst?(pokemon.item,PBItems,:DRACOPLATE,:DRAGONIUMZ)
   next 17 if isConst?(pokemon.item,PBItems,:DREADPLATE,:DARKINIUMZ)
   next 18 if isConst?(pokemon.item,PBItems,:PIXIEPLATE,:FAIRIUMZ)
   next 19 if isConst?(pokemon.item,PBItems,:SHADOWPLATE,:SHADOWIUMZ)
   next 20 if isConst?(pokemon.item,PBItems,:VOIDPLATE,:VOIDIUMZ)
   next 0
}
})

It's giving me this argument error but I'm not sure what exactly needs changing:

[Pokémon Essentials version 17.1]
Exception: ArgumentError
Message: wrong number of arguments(4 for 3)
Pokemon_Forms:369:in `isConst?'
Pokemon_Forms:369
Pokemon_Forms:368:in `call'
Pokemon_Forms:95:in `call'
Pokemon_Forms:7:in `form'
Pokemon_Forms:28:in `fSpecies'
PokeBattle_Pokemon:848:in `baseStats'
PokeBattle_Pokemon:884:in `calcStats'
Pokemon_Forms:18:in `form='
Debug_Pokemon:491:in `pbPokemonDebugActions'

Should I change the last part to an array of some sort? This will probably be my last custom scripts question for a long while. As always, any help is appreciated. Thanks.

Edit: I guess I could just do the same line twice in Pokemon_Forms; one with item that's already there, and the one I want to add, but surely there must be an easier way?

Nevermind, I got what I wanted it to do the long way by individually writing a new line for each Z-Crystal.

Have you tried this?

next 1 if isConst?(pokemon.item,PBItems,:FISTPLATE) || isConst?(pokemon.item,PBItems,:FIGHTINIUMZ)
