[Question] Steel doesnt exist i guess?

when playtesting my game for the first time i got this error

[Pokémon Essentials version 19.1]

Exception: RuntimeError
Message: Undefined value Steel in GameData::Type
File PBS/pokemon.txt, section 9, key Type2
Steel



Backtrace:

how do i fix this?

It's an internal name, so you'll need to capitalise the word "Steel". Write it as STEEL.

oh thanks i retyped blastoise to water/steel so i must have forgot that
