Attempted to index a nil value?

I get the following error when I try to update the display that tells the player how much money they have:

15:32.798 - ServerScriptService.DataManager:47: attempt to index field '?' (a nil value)
15:32.798 - Stack Begin
15:32.799 - Script 'ServerScriptService.DataManager', Line 47
15:32.800 - Stack End

Script inside the serverscriptservice:

01local DS = game:GetService("DataStoreService")
02local Players = game:GetService("Players")
03local Run = game:GetService("RunService")
04 
05local playerDataStore = DS:GetDataStore("PlayerData")

The script that updates the player's currency display:

1local Display = script.Parent.MainGui.CashBox.Cash
2local UpdEve = game.ReplicatedStorage.UpdateCash
3 
4UpdEve.OnClientEvent:Connect(function(amount)
5    Display.Text = amount
6end)

What is causing the error and how do I fix it? And by the way, am I doing datascripts right so far?
