How to access and change the value of cash that is in a table from another script?

Hello helpers,

I am learning scripting still so please don't be too hard on me if there is a simple solution to this or if there is a better way.

I have this Datastore script that I followed from the tutorial here https://www.youtube.com/watch?v=FgcWmYhi7I8 (I understand pretty much everything in it so I didn't just copy and paste it..)

Basically when the player joins it checks if the player has data and if not it runs newData which is a table that is a template for the data that needs to be stored. The data is then stored to ServerData

How would I access for example "Cash" to change the value of it from another script?

Here is the code

--services 
local Players = game:GetService("Players")

local DataService = game:GetService("DataStoreService")
local PlayerData = DataService:GetDataStore("PlayerData") 

--variables
local ServerData = {}
local SavingFor = {}

--functions

local function newData() --template for what the data is
	return {
		Cash = 200,
		tWood =150,
		Stats = {
			Speed = 16,
			Jump = 50,
		},
	}
end

local function loadData(player)
	local data
	local Success, Error = pcall(function() data = PlayerData:GetAsync("data:"..player.UserId) end) -- if servers are down it will not break
	
	if not Success then 
		warn("	Could not get data for "..player.Name)
		return
	end
	
	if not data then -- if player is new (no data in pcall) the new data equals the new data template
		data = newData()
	end 
	
	ServerData[player] = data
	
end

local function saveData(player)
	
	if not SavingFor[player] then	
		SavingFor[player] = true
		
		if ServerData[player] then
			local Success, Error = pcall(function() PlayerData:SetAsync("data:"..player.UserId, ServerData[player]) end)
			
			if not Success then
				warn("Data wasn't saved for"..player.Name.."!")
				return
			end
			
				ServerData[player] = nil
		end
		
		SavingFor[player] = nil
	end
end

Players.PlayerAdded:Connect(function(player)
	loadData(player)
end)

Players.PlayerRemoving:Connect(function(player)
	saveData(player)
end)

game:BindToClose(function()
	for i,player in pairs (Players:GetChildren()) do
		saveData(player)
	end
end)

Thank you in advance
