Food mod modification

[ThatOneMajora]

Basically I got a food mod for darkrp, but players can go over 100HP when eating it. I wanted to make a fix and found a bit of code which I added (hopefully correctly) and now I get this error.

04:00:25 Lua Error: [ERROR] addons/majorafood/lua/entities/toffifee/init.lua:43: attempt to index global 'ply' (a nil value) 1. fn - addons/majorafood/lua/entities/toffifee/init.lua:43 2. unknown - addons/ulib/lua/ulib/shared/hook.lua:110

Here is the line in question

function HealthBelow100()

   for k,v in pairs( player.GetAll() ) do
       if ply:Health() > 100 then
            ply:SetHealth( 100 )
       end
   end

end

hook.Add( "Think", "HpBelow100", HealthBelow100 )

What am I doing wrong? Thanks :)

The ENTIRE init.lua in question

AddCSLuaFile( "shared.lua" )
include( 'shared.lua' )

function ENT:SpawnFunction( ply, tr )
	
	if !tr.Hit then return end

	local SpawnPos = tr.HitPos + tr.HitNormal * 1

	local ent = ents.Create( "Toffifee" )
	ent:SetPos( SpawnPos )
	ent:Spawn()
	ent:Activate()
	
	return ent
end

function ENT:Initialize()

	self.Entity:SetModel("models/FoodNHouseholdItems/toffifee.mdl")
 
	self.Entity:PhysicsInit( SOLID_VPHYSICS )
	self.Entity:SetMoveType( MOVETYPE_VPHYSICS )
	self.Entity:SetSolid( SOLID_VPHYSICS )

	
	self.Index = self.Entity:EntIndex()
	
	local phys = self.Entity:GetPhysicsObject()
	if phys:IsValid() then
		phys:Wake()
	end
end

function ENT:Use(activator)
	self.Entity:Remove()
	activator:EmitSound("eating_and_drinking/eating_long.wav", 50, 100)

end
function HealthBelow100()

   for k,v in pairs( player.GetAll() ) do
       if ply:Health() > 100 then
            ply:SetHealth( 100 )
       end
   end

end

hook.Add( "Think", "HpBelow100", HealthBelow100 )
