So I made a sword for killing Zombie humanoids
It works but after a while occasionally it will pop up with this error:

18:03:02.716 - TakeDamage is not a valid member of Model
18:03:02.717 - Script 'Workspace.ZombieSword.SwordScript', Line 47
18:03:02.717 - Stack End

Heres the SwordScript:

r = game:service("RunService")


local damage = 4


local slash_damage = 8
local lunge_damage = 25

sword = script.Parent.Handle
Tool = script.Parent


local SlashSound = Instance.new("Sound")
SlashSound.SoundId = "rbxasset://sounds\\swordslash.wav"
SlashSound.Parent = sword
SlashSound.Volume = .7

local LungeSound = Instance.new("Sound")
LungeSound.SoundId = "rbxasset://sounds\\swordlunge.wav"
LungeSound.Parent = sword
LungeSound.Volume = .6

local UnsheathSound = Instance.new("Sound")
UnsheathSound.SoundId = "rbxasset://sounds\\unsheath.wav"
UnsheathSound.Parent = sword
UnsheathSound.Volume = 1


function blow(hit)
if (hit.Parent == nil) then return end -- happens when bullet hits sword

local humanoid = hit.Parent:findFirstChild("Zombie")
local vCharacter = Tool.Parent
local vPlayer = game.Players:playerFromCharacter(vCharacter)
local hum = vCharacter:findFirstChild("Humanoid") -- non-nil if tool held by a character
if humanoid~=nil and humanoid ~= hum and hum ~= nil then
-- final check, make sure sword is in-hand

local right_arm = vCharacter:FindFirstChild("Right Arm")
if (right_arm ~= nil) then
local joint = right_arm:FindFirstChild("RightGrip")
if (joint ~= nil and (joint.Part0 == sword or joint.Part1 == sword)) then
tagHumanoid(humanoid, vPlayer)
humanoid:TakeDamage(damage)
wait(1)
untagHumanoid(humanoid)
end
end


end
end


function tagHumanoid(humanoid, player)
local creator_tag = Instance.new("ObjectValue")
creator_tag.Value = player
creator_tag.Name = "creator"
creator_tag.Parent = humanoid
end

function untagHumanoid(humanoid)
if humanoid ~= nil then
local tag = humanoid:findFirstChild("creator")
if tag ~= nil then
tag.Parent = nil
end
end
end


function attack()
damage = slash_damage
SlashSound:play()
local anim = Instance.new("StringValue")
anim.Name = "toolanim"
anim.Value = "Slash"
anim.Parent = Tool
end

function lunge()
damage = lunge_damage

LungeSound:play()

local anim = Instance.new("StringValue")
anim.Name = "toolanim"
anim.Value = "Lunge"
anim.Parent = Tool


force = Instance.new("BodyVelocity")
force.velocity = Vector3.new(0,10,0) --Tool.Parent.Torso.CFrame.lookVector * 80
force.Parent = Tool.Parent.Torso
wait(.25)
swordOut()
wait(.25)
force.Parent = nil
wait(.5)
swordUp()

damage = slash_damage
end

function swordUp()
Tool.GripForward = Vector3.new(-1,0,0)
Tool.GripRight = Vector3.new(0,1,0)
Tool.GripUp = Vector3.new(0,0,1)
end

function swordOut()
Tool.GripForward = Vector3.new(0,0,1)
Tool.GripRight = Vector3.new(0,-1,0)
Tool.GripUp = Vector3.new(-1,0,0)
end

function swordAcross()
-- parry
end


Tool.Enabled = true
local last_attack = 0
function onActivated()

if not Tool.Enabled then
return
end

Tool.Enabled = false

local character = Tool.Parent;
local humanoid = character.Humanoid
if humanoid == nil then
print("Humanoid not found")
return
end

t = r.Stepped:wait()

if (t - last_attack < .2) then
lunge()
else
attack()
end

last_attack = t

--wait(.5)

Tool.Enabled = true
end


function onEquipped()
UnsheathSound:play()
end


script.Parent.Activated:connect(onActivated)
script.Parent.Equipped:connect(onEquipped)


connection = sword.Touched:connect(blow)


basically its a linked sword that kills zombies.

Instead of :TakeDamage, try
humanoid.health = (humanoid.health - damage)

then you have humanoid set as an incorrect variable. Humanoid is not a model
