How I can do to make my HM Item compatible with the Follow Pokémon Script?

[JolTH]

I edit the PField_HiddenMoves on Essentials 16.2 to use a Sharpedo Bot to replace Surf, it works fine but when I use the mej71's Following Pokémon Script it doesn't work, only the Debug Surf. What I can do to make this work with that script on? I ask it on his post a week ago but got no reply.

Here is the code:

#===============================================================================
# Surf
#===============================================================================
def Kernel.pbSurf
  
if ($DEBUG || $PokemonBag.pbQuantity(PBItems::SHARPEDO) > 0 || movefinder=Kernel.pbCheckMove(:SURF)) && $game_switches[4]
    if ($DEBUG || movefinder || $PokemonBag.pbQuantity(PBItems::SHARPEDO) > 0) && $game_switches[4]
      if $PokemonBag.pbQuantity(PBItems::SHARPEDO) > 0
         Kernel.pbMessage(_INTL("The Sharpedo Bot pack is vibrating!"))
      else
        Kernel.pbMessage(_INTL("The water is dyed a deep blue..."))
      end
      if Kernel.pbConfirmMessage(_INTL("Would you like to surf?"))
        speciesname=!movefinder ? $Trainer.name : movefinder.name
        Kernel.pbMessage(_INTL("{1} used Surf!",speciesname))
        pbHiddenMoveAnimation(movefinder)
        surfbgm=pbGetMetadata(0,MetadataSurfBGM)
        if surfbgm
          pbCueBGM(surfbgm,0.5)
        end
        pbStartSurfing()
        return true
      end
    end
  else
    Kernel.pbMessage(_INTL("The water is dyed a blue..."))
  end
  return false
end
