[Error] Eevee's Form-Changing ability should work but doesn't. Why?

[SuperSpyroDragon64]

This code is in Battler_UseMove. It is inspired by the code Aegislash's ability Stance Change uses to change his form.

    if isSpecies?(:EEVEE) && self.ability == :EEVEELUTION
          move.calcType = move.pbCalcType(self)
        if move.calcType == :WATER
        pbChangeForm(1, _INTL("{1} Eevolved into Vaporeon!", pbThis))
                elsif move.calcType = :ELECTRIC
        pbChangeForm(2, _INTL("{1} Eevolved into Jolteon!", pbThis))
                        elsif move.calcType = :FIRE
        pbChangeForm(3, _INTL("{1} Eevolved into Flareon!", pbThis))
end
end

I have copypasted Vaporeon, Jolteon, and Flareon into the Pokemon_Forms PBS under their respective numbers. This script looks okay to me but it does nothing ingame. I ensured EEVEELUTION is the only ability Eevee can have, and I ensured it is the ability the Eevee in my party has when playtesting. Everything looks like it should work.

The only bugs I can see is the single = in the elsif statements—they need to be ==.

I fixed that but it's still not working. When my Eevee uses Flamethrower, Surf, or Thunder, nothing happens.

 isSpecies?(:EEVEE) && self.ability == :EEVEELUTION
          move.calcType = move.pbCalcType(self)
        if move.calcType == :WATER
        pbChangeForm(1, _INTL("{1} Eevolved into Vaporeon!", pbThis))
                elsif move.calcType == :ELECTRIC
        pbChangeForm(2, _INTL("{1} Eevolved into Jolteon!", pbThis))
                        elsif move.calcType == :FIRE
        pbChangeForm(3, _INTL("{1} Eevolved into Flareon!", pbThis))
end
end
