Why is the damage script being ignored?

I made a shop GUI, and players are able to buy swords from it.

When someone first buys a sword, the damage script inside of the sword is being completely ignored for some reason.

I changed the it to a local script and it started to work fine.

I was wondering why was the damage script being ignored? If the player resets then the damage script works just fine, but when first buying the sword it isn't being run at all.

ShopGUI script:

local katanaButton = script.Parent
local player = game.Players.LocalPlayer
local replicatedStorage = game:GetService("ReplicatedStorage")
local storedKatana = game.replicatedStorage.Katana


katanaButton.MouseButton1Click:connect(function()
	if player.Backpack.Money.Value >= 100 and not player.Character:FindFirstChild("Katana") then
		
		local Katana = storedKatana:Clone()
		Katana.Parent = player.Character
		local RootPart = player.Character:FindFirstChild("HumanoidRootPart")

		Katana.CFrame = player.Character:FindFirstChild("Left Leg").CFrame * CFrame.new(-.6, .2, 1.7)
		Katana.CFrame = Katana.CFrame * CFrame.Angles(.3, 0, 1.5)
		
		local weld = Instance.new("Weld")
		weld.Part0 = RootPart
		weld.C0 = RootPart.CFrame:inverse()
		weld.Part1 = Katana
		weld.C1 = Katana.CFrame:inverse()
		weld.Parent = Katana
		
		player.Backpack.Money.Value = player.Backpack.Money.Value - 100

		script.Parent.Parent.TextLabel.Text = "Thank you, for your purchase!"
		wait(2)
		script.Parent.Parent.TextLabel.Text = "Sword Shop"

		local sword = Instance.new("StringValue")
		sword.Parent = player.StarterGear
		sword.Name = "Sword"
		sword.Value = "Katana"
		

	else
		if player.Character:FindFirstChild("Katana") then
			script.Parent.Parent.TextLabel.Text = "You already bought a Katana"
			wait(2)
			script.Parent.Parent.TextLabel.Text = "Sword Shop"
		elseif player.Backpack.Money.Value <= 100 then
			local cashreq = 100 - player.Backpack.Money.Value
			script.Parent.Parent.TextLabel.Text = "You need "..cashreq.." more money to purchase this"
			wait(2)
			script.Parent.Parent.TextLabel.Text = "Sword Shop"
		else
			script.Parent.Parent.TextLabel.Text = "Something went wrong with the script"
			wait(2)
			script.Parent.Parent.TextLabel.Text = "Sword Shop"
		end

		
	end
end)

Respawn script:

replicatedStorage = game:GetService("ReplicatedStorage")
storedKatana = game.replicatedStorage.Katana

game.Players.PlayerAdded:connect(function(player)
	local sword = player:WaitForChild("StarterGear"):WaitForChild("Sword")
	if sword then
		if sword.Value == "Katana" then
			player.CharacterAdded:connect(function(character)
				local Katana = storedKatana:Clone()
				Katana.Parent = player.Character
				local RootPart = player.Character:FindFirstChild("HumanoidRootPart")

				Katana.CFrame = player.Character:FindFirstChild("Left Leg").CFrame * CFrame.new(-.6, .2, 1.7)
				Katana.CFrame = Katana.CFrame * CFrame.Angles(.3, 0, 1.5)
			
				local weld = Instance.new("Weld")
				weld.Part0 = RootPart
				weld.C0 = RootPart.CFrame:inverse()
				weld.Part1 = Katana
				weld.C1 = Katana.CFrame:inverse()
				weld.Parent = Katana
			

			end)
		else
			print("something went wrong! 2")
		end
	else
		print("Something went wrong! 1")
	end
end)

Damage Script:

katana = script.Parent
player = game.Players.LocalPlayer
swingDamage = script.Parent.SwordDamage.Value
CanDamage = true





katana.Touched:connect(function(hit)
	local humanoid = hit.Parent:WaitForChild("Humanoid")

	if humanoid then
		if humanoid.Parent.Name ~= script.Parent.Parent.Name and CanDamage and script.Parent.Swinging.Value == true then
			CanDamage = false
			humanoid:TakeDamage(swingDamage + script.Parent.Combo.Value)
			print("Dealt ", swingDamage + script.Parent.Combo.Value, " damage")
			wait(1)
			CanDamage = true
		else
			print("something went wrong2")
		end
	else
		print("something went wrong1")
	end
	print("something went wrong0")
end)
