How does creator tag work and how can I use it on this weapon(my attempt)?

So this is the main part of the flamethrower. the "mouse.Button1Down" is another function that makes fire enabled and clones the damage script. How can I make it so when you kill someone, it gets added to your KOs? Here's the main gun script and the damage script:

I added creator tags to them, but it isn't working! (The equipped script is a local script)

plr = game.Players.LocalPlayer
creator = Instance.new("ObjectValue")
creator.Name = "creator"
creator.Value = plr

Tool.Equipped:connect(function(mouse)
    local Humanoid = script.Parent.Parent.Humanoid
    Humanoid.WalkSpeed = 10
    mouse.Icon="rbxasset://textures\\GunCursor.png"
    animation = Instance.new("Animation")
    animation.AnimationId = "http://www.roblox.com/Asset?ID=331030667"
    animTrack = Humanoid:LoadAnimation(animation)
    animTrack:Play()

    mouse.Button1Down:connect(function() MouseDown(mouse) end)
    mouse.Button1Up:connect(function() MouseUp(mouse) end)

    grip = Instance.new("Weld",script.Parent.Parent.Torso)
    grip.Part0 = script.Parent.Parent.Torso
    grip.Part1 = script.Parent.Handle
    grip.C0 = CFrame.new(0,0,-2)*CFrame.Angles(math.rad(10),math.rad(20),0)
    grip.Name = "Grip"

    while wait() do
    if script.Parent.Parent:FindFirstChild("Right Arm")then
        for _,v in pairs(script.Parent.Parent["Right Arm"]:GetChildren())do
            if v.Name == "RightGrip" then
                game.Debris:AddItem(v,0)
                break
            end
        end
    end
    end
end)
Tool.Unequipped:connect(function()
    fire1.Enabled = false
    fire2.Enabled = false   
    fire3.Enabled = false
    animTrack:Stop()
    game.Debris:AddItem(animation,0)
    game.Debris:AddItem(grip,0)
    script.Parent.Parent.Parent.Character.Humanoid.WalkSpeed = 16
end)

^^^^^^^^^ These are two different scripts vvvvvvvvv

brick = script.Parent
debounce = false
-- Variables

brick.Touched:connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") and not debounce then
        debounce = true
        local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
        local hum = hit.Parent.Humanoid
        if not plr and hum.Health > 0 and hit.Parent.Torso.Anchored == false and hit.Parent.Name ~= "Vault" and hit.Parent.Name ~= "Soldier" and hit.Parent.Name ~= "" and hit.Parent.Name ~= " " and hit.Parent.Name ~= "Governor" and hit.Parent.Name ~= "Emperor" then
            local ice = Instance.new("Part")
            hit.Parent.Torso.Anchored = true
            ice.Anchored = true
            ice.Transparency = 0.3
            ice.BrickColor = BrickColor.new("Teal")
            ice.BottomSurface = "Smooth"
            ice.TopSurface = "Smooth"
            ice.Size = Vector3.new(5,8,5)
            ice.CFrame = CFrame.new(hit.Parent.Torso.CFrame.p)
            ice.Parent = hit
            local filt1 = script.Parent.filter:Clone()
            filt1.Parent = ice
            filt1.Disabled = false
            local tag=creator:clone()
            tag.Parent=Hum
            hit.Parent.Humanoid:TakeDamage(50)
        elseif plr and hum.Health > 0 and hit.Parent.Torso.Anchored == false and plr.TeamColor ~= BrickColor.new("Bright blue") then
            local ice = Instance.new("Part")
            ice.Size = Vector3.new(5,8,5)
            script.Parent.Parent.Torso.Anchored = true
            ice.Anchored = true
            ice.Transparency = 0.3
