So 2 things that I notice are wrong at the moment. When I go into the game it does not make the PlayerData name file, and the equipped file. It is also not letting me open the GUI when I push the open Button. This is what I got so far.

Stats Script:

local datastores = game:GetService("DataStoreService") :getdatastore("CashDataStore")
local defaultcash = 50
local playersLeft = 0

game.Players.PlayerAdded:Connect(function(player)

playersLeft = playersLeft + 1

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

local cash = Instance.new("IntValue")
cash.Name = "Cash"
cash.Value = 0
cash.Parent = leaderstats


local playerdata = Instance.new("Folder")
playerdata.Name = player.Name
playerdata.Parent = game.ServerStorage.PlayerData

local equipped = Instance.new("StringValue")
equipped.Name = "Equipped"
equipped.Parent = PlayerData

local inventory = Instance.new("Folder")
inventory.Name = "Inventory"
inventory.Parent = PlayerData

local player_data
local weaponsdata
local equippeddata

pcall(function()
	player_data = datastores:getasync(player.userid.."-Cash")
end)

pcall(function()
	weaponsdata = datastores:getasync(player.userid.."-Weps")
	end)

pcall(function()
	equippeddata = datastores:getasync(player.userid.."-EquippedValue")
	end)
	
	if player_data ~= nil then
		--player has saved data , load it in
		cash.value = player_data
	else
		Cash.Value = defaultcash
	end
	
	if weaponsdata then
		
		--later
		
		
	end
	
end)

local bindableEvent = Instance.new("BindableEvent")

game.Players.PlayerRemoving:Connect(function(player)

pcall(function()
	datastores:setasync(player.userid.."-Cash",player.leaderstats.Cash.Vaule)
	print("Saved")
	playerLeft = playerLeft - 1
	bindableEvent:fire()
end)

end)

game:BindToClose(function()
while playerLeft > 0 do
	bindableEvent.Event:Wait()
end
end)

ServerHandler Script:

game.ReplicatedStorage:WaitForChild("GetTools").OnServerInvoke = function(player)
local items = {}

for _, object in pairs(game.ServerStorage:WaitForChild("Items"):GetChildren()) do
	local itemProperties = {object.Name,object.Price.Value}
	table.insert(items,itemProperties)
end

return items
end

Core Script: 

-- Core UI localscript

local availableTools = game.ReplicatedStorage:WaitForChild("GetTools"):InvokeServer()
local mainFrame = script.Parent:WaitForChild("MainFrame")
local safeArea = mainFrame:WaitForChild("SafeArea")
local itemInformation = safeArea:WaitForChild("ItemInformation")
local infoFrame = itemInformation.InfoFrame
local selectedItem = itemInformation.SelectedItem
local equippedItem = itemInformation.EquippedItem
local numberOfItems = #availableTools

local itemFrame = safeArea.ItemFrame
local shopButton = script.Parent:WaitForChild("ShopButton")
local buyButton = infoFrame.BuyButton
local equippedItemViewport = script.Parent:WaitForChild("EquippedItemViewport")
local itemViewport = itemInformation.ItemViewport
