Why gets everyplayer an amount of cash when one single player is clicking a tool?

I think it has something to do with the remote event.

The server event script for the tool:

local liftSwordEvent =  game.ReplicatedStorage.RemoteEvents:WaitForChild("LiftSword")


liftSwordEvent.OnServerEvent:Connect(function(player,cashIncreaseValue)
	local cash = game.Players[script.Parent.Parent.Name].leaderstats.Cash
	
	for i, toolsInCharacter in pairs(script.Parent.Parent:GetChildren()) do
		
		if toolsInCharacter and toolsInCharacter:IsA("Tool") then
			local cashIncrease = toolsInCharacter:WaitForChild("CashIncrease")
			
			local multiplier = toolsInCharacter:WaitForChild("CashMultiplier")
			
			if multiplier then
				cash.Value = cash.Value + cashIncrease.Value * multiplier.Value
			end		
		end
		end
end)

The local script for the tool:

local sword = script.Parent
local liftSwordEvent = game.ReplicatedStorage.RemoteEvents:WaitForChild("LiftSword")

sword.Activated:Connect(function()
	if sword.Parent == game.Players.LocalPlayer.Character then
		liftSwordEvent:FireServer()
	end
end)

The leaderstats script

game.Players.PlayerAdded:Connect(function(player)
	local folder = Instance.new("Folder",player)
	folder.Name = "leaderstats"
	
	local cash = Instance.new("IntValue",folder)
	cash.Name = "Cash"
	cash.Value = 1500
	
	local weaponsOwned = Instance.new("Folder",player)
	weaponsOwned.Name = "weaponsowned"
	
	local sword1owned = Instance.new("BoolValue",weaponsOwned)
	sword1owned.Name = "Sword1owned"
	sword1owned.Value = false
	
	local sword2owned = Instance.new("BoolValue",weaponsOwned)
	sword2owned.Name = "Sword2owned"
	sword2owned.Value = false
end)

Thanks!
