    Given the fact that line 483 does not exist in a clean v17.2 project, It appears that you have added some new code, probably a new form.
    The error itself is saying you tried to check if nil is less than a number or variable but you should really post the code if you want more help than that.

    this is the script editor. Each item on the left menu pulls of up a script that does something with the code. in the right half is where the code's text editor is. those little numbers in gray mean which line of the code youre on. You can copy, paste, the text into the code editor into any program that reads text like here.

    • that does appear to be the problem code, and ruby doesn't like "<" for some reason, which is the correct operator. does it return an error if you replace "<1" with "==0" and ">254" with "==255"?

    The problem seems to be that you are calling this method on a pokémon who's happiness has not yet been initialized and is thus nil. The < operator doesn't work for nil. Try changing your code to this:
    Code: 
    MultipleForms.register(:EMOMOTH,{
"getForm"=>proc{|pokemon|
next 2 if !pokemon.happiness >=1
next 1 if pokemon.happiness>254
next 0 
}
})

    Hmm, doesn't that cause a "true has no >= operator" error, because !nil is true, and true can't be compared with numbers?

    I think you'd be better off with something like:
    Code: 
    MultipleForms.register(:EMOMOTH,{
"getForm"=>proc{|pokemon|
next 0 if pokemon.happiness.nil?
next 2 if pokemon.happiness<1
next 1 if pokemon.happiness>254
next 0 
}
})
    Or maybe that first next should be next 2? Not sure under what circumstances a Pokémon's happiness can be nil, and therefore what form is most appropriate.

    Just to answer this question, you can compare nil with anything, so it will work fine, assuming that happiness cannot be less than 0 or more than 255 (which sounds right).
    I think this solution is cleaner than Poq's/my suggestion involving nil?, but YMMV.

    That sounds like a good idea. Although ideally you'd want to work out why it's nil before you do that, because I'd expect that happiness should always be initialized to the base happiness instead of nil.

    • Maybe he needs to add:

    Code: 
    attr_accessor(:happiness)

    Inside '_Forms' script. Like:
    Code: 
    class PokeBattle_Pokemon
  attr_accessor(:formTime)   # Time when Furfrou's/Hoopa's form was set
  attr_accessor(:forcedForm)
  attr_accessor(:happiness)

    Because the code that i sent to him is correct, i guess lol. It was the same than i made to Lycanroc.
