Value not being subtracted?

Help and Feedback Scripting Support
1

Im making a bounty system for a game, right now im working on after the player has been killed 20 precent of the killed players bounty goes to the the player that killed him. Adding the Value works just fine but when subtracting the value from the player who died it adds a random amount then it subtracts back to what it orginally was making the value not go down at all. Its really werid heres my script for it.

local DataStoreService = game:GetService("DataStoreService")
local Players = game:getService("Players")

--//DataStore
local CurrencyData = DataStoreService:GetDataStore("BountyData")

--//Configuration
local CurrencyName = "Bounty"
local StartingValue = 10000
local playerkilledremote = game.ReplicatedStorage.Remotes.PlayerKilled

Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(Char)

		local UserData
		local success, errMsg = pcall(function()
			UserData = CurrencyData:GetAsync(player.UserId) 
		end)

		if success == false then 
			local doNotSave = Instance.new("Folder")
			doNotSave.Name = "DoNotSave"
			doNotSave.Parent = player

		else
			print("Data loaded!") 
		end

		local leaderstats = Instance.new("Folder")  
		leaderstats.Name = "leaderstats" 
		leaderstats.Parent = player

		local Bounty = Instance.new("IntValue") 
		Bounty.Name = CurrencyName
		Bounty.Value = UserData or StartingValue 
		Bounty.Parent = leaderstats 
		Char:WaitForChild("Humanoid").Died:Connect(function()
			for _, v in pairs(game.Workspace.Players:GetChildren()) do
				local previousname = nil
				if previousname == nil or previousname ~= v.Name then
					previousname = v.Name
				local otherplayer = game.Players:WaitForChild(v.Name)
				local charbounty = player:WaitForChild("leaderstats").Bounty.Value
				local PlayerData = _G["ASODUFON!)@$JV)S_DFN@)$!J@!#G}ASDFL#$%SAS_DF@?#$!@ - "..player.Name]
				local OplayerData = _G["ASODUFON!)@$JV)S_DFN@)$!J@!#G}ASDFL#$%SAS_DF@?#$!@ - "..otherplayer.Name]
				local bountyop = otherplayer.leaderstats.Bounty
					
				if PlayerData.Level.Value - OplayerData.Level.Value >= 100 then return end
				
				bountyop.Value = bountyop.Value + (charbounty * 0.2)
				charbounty = charbounty - (charbounty * 0.2)
				end
previousname = nil
			end

		end)
	end)
end)

Players.PlayerRemoving:Connect(function(player) 
	local SavingPath = player.leaderstats:FindFirstChild(CurrencyName) 

	if player:FindFirstChild("DoNotSave") then 
		warn("Player data was not saved to avoid data loss.")
	else
		CurrencyData:SetAsync(player.UserId, SavingPath.Value) 
	end
end)

any help is appericated!!
