I need help with setting value to player

[noobforlifeisanoob]

Basically i just want to add creator tag so i can add a kill point for my sword but i don’t know how to add creator tag value to player here script local Debris = game:GetService(“Debris”)
local damage = 10
local debounce = true
local tool = script.Parent

Players = game:GetService(“Players”)
function tagHumanoid(hum, player)
if hum and hum:IsA(“Humanoid”) then
local existingTag = hum:FindFirstChild(“creator”)
if existingTag then
existingTag:Destroy()
end

	local tag = Instance.new("ObjectValue")
	tag.Name = "creator"
	tag.Value = player
	Debris:AddItem(tag, 2)
	tag.Parent = hum
	
end

end

function attack(Player)
print(“attack function called”)
local hitbox = script.Parent
hitbox.Touched:Connect(function(hit)

	local humanoid = hit.Parent:FindFirstChild("Humanoid")

	if humanoid and debounce then
		humanoid:TakeDamage(damage)
		local character = hit.Parent
		local player = Players:GetPlayerFromCharacter(character)
		print("damaged humanoid by " .. damage)
		tagHumanoid(humanoid, Player) 
		debounce = false
		wait(1)
		debounce = true
	end
end)

end

script.Parent.Parent.Activated:Connect(function()
local success, err = pcall(function()
end)
if success then
attack()
end
end)

script.Parent.Parent.Activated:Connect(function()
    local success, err = pcall(function()
    end)
    if success then
        attack()
    end
end)

You’re not passing an argument when you call attack(), so Player inside the attack() function is nil, which is being sent to the tagHumanoid() function.

And was it intentional that you typed script.Parent.Parent.Activated instead of script.Parent.Activated or tool.Activated when you defined tool as script.Parent, not script.Parent.Parent?
You are also using script.Parent for hitbox inside of the attack() function:

local function attack(Player)
    print("attack function called")
    local hitbox = script.Parent
    -- ...
end

Just Formatted it a bit

local Debris = game:GetService(“Debris”)
local damage = 10
local debounce = true
local tool = script.Parent

Players = game:GetService(“Players”)
function tagHumanoid(hum, player)
if hum and hum:IsA(“Humanoid”) then
local existingTag = hum:FindFirstChild(“creator”)
if existingTag then
existingTag:Destroy()
end


	local tag = Instance.new("ObjectValue")
	tag.Name = "creator"
	tag.Value = player
	Debris:AddItem(tag, 2)
	tag.Parent = hum
	
end


end



function attack(Player)
print(“attack function called”)
local hitbox = script.Parent
hitbox.Touched:Connect(function(hit)


	local humanoid = hit.Parent:FindFirstChild("Humanoid")

	if humanoid and debounce then
		humanoid:TakeDamage(damage)
		local character = hit.Parent
		local player = Players:GetPlayerFromCharacter(character)
		print("damaged humanoid by " .. damage)
		tagHumanoid(humanoid, Player) 
		debounce = false
		wait(1)
		debounce = true
	end
end)


end

script.Parent.Parent.Activated:Connect(function()
local success, err = pcall(function()
end)
if success then
attack()
end
end)
