Attempt to index local money (a nil value)?

Alright, I've made a datastorage script but it is completely ignoring the value, I understand what the issue is, the value for some reason "doesn't exist" but I dont know how to fix it, Its clear that the **SERVERSCRIPT ** is unable to access it, where else would I put it (i tried in character, but it ignores the value)

btw this error has NOTHING to do with datastorage , any help? (ps the cash is inside StarterPlayerScripts that is then inside PlayerScripts i cant access playerscripts but idk where else to put it)

local ReplicatedStorage = game:GetService("ReplicatedStorage")
saveMoneyEvent = game.ReplicatedStorage.saveMoneyEvent
HttpService = game:GetService("HttpService")

local function onSaveMoneyFired(player, money)
print ("saving...")
player:FindFirstChild('cash').Value = money --issue
local databaseService = require(game.ServerScriptService.DatabaseService)
local globalDatabase = databaseService:GetDatabase("Global")
print (money)  --issue via chain reaction
local frank = HttpService:JSONEncode(money)  --issue via chain reaction
print(frank)  --issue via chain reaction
print(HttpService:JSONDecode(frank))  --issue via chain reaction
globalDatabase:PostAsync(player.Name, frank)  --issue via chain reaction
end


saveMoneyEvent.OnServerEvent:Connect(onSaveMoneyFired)
