My Roblox Studio script is sometimes having errors.. idk why - macos

Question

So.. I've been coding to make a GUI show the quantity of currency of a player, the datastore API works perfectly but the local script doesn't (it's local because else it would just update it each time a player's currency gets updated and would be a mess being the opposite of what I want to)
and well... sometimes it loads the currency into the GUI but other times it just stays on the original text: "Label" instead of my current currency (4600)
here's the proof
What normally happens and should always happen
What sometimes happens and shouldn't happen:
here's the script, I've tried putting waits on the start but the original code is inside the while true do..
wait(game.Players.LocalPlayer:WaitForChild("Data")
wait(game.Players.LocalPlayer.Data:WaitForChild("Bells"))
while true do
script.Parent.TextLabel.Text = game.Players.LocalPlayer:WaitForChild("Data"):WaitForChild("Bells").Value
wait() --wait is for not making the loop break and stop the whole script
end
well.. if you want to see if data is really in the player, here's the script, it requires a API (DataStore2)
--[Animal Crossing Roblox Edition Data Store]--

--Module not mine--
--Made with a AlvinBlox tutorial--
--·.·.*[Get Data Store, do not erase]*.·.·--
local DataStore2 = require(1936396537)
--[Default Values]--
local DefaultValue_Bells = 300
local DefaultValue_CustomClothes = 0
--[Data Store Functions]--
game.Players.PlayerAdded:Connect(function(player)
--[Data stores]--
local BellsDataStore = DataStore2("Bells",player)
local Data = Instance.new("Folder",player)
Data.Name = "Data"
Bells = Instance.new("IntValue",Data)
Bells.Name = "Bells"
local CustomClothesDataStore = DataStore2("CustomClothes",player)
local CustomClothes = Instance.new("IntValue",Data)
CustomClothes.Name = "CustomClothes"
local function CustomClothesUpdate(UpdatedValue)
CustomClothes.Value = CustomClothesDataStore:Get(UpdatedValue)
end
local function BellsUpdate(UpdatedValue)
Bells.Value = BellsDataStore:Get(UpdatedValue)
end
BellsUpdate(DefaultValue_Bells)
CustomClothesUpdate(DefaultValue_CustomClothes)
BellsDataStore:OnUpdate(BellsUpdate)
CustomClothesDataStore:OnUpdate(CustomClothesUpdate)
end)
--[test and reference functions]--
workspace.TestDevPointGiver.ClickDetector.MouseClick:Connect(function(player)
local BellsDataStore = DataStore2("Bells",player)
BellsDataStore:Increment(50,DefaultValue_Bells)
end)
workspace.TestDevCustomClothesGiver.ClickDetector.MouseClick:Connect(function(player)
local CustomClothesDataStore = DataStore2("CustomClothes",player)
CustomClothesDataStore:Increment(50,DefaultValue_CustomClothes)
end)
the code that creates "Data" and "Bells" is located in the comment: Data Stores
the only script that gets the issue is the short one with no reason :<
I hope that you can help me :3
#Night94 I tryed your script but it also failed sometimes

Answer 1

The syntax in your LocalScript is a little off with the waits. With that fixed, it works every time. Also, I would use an event handler instead of updating the value with a loop:
game.Players.LocalPlayer:WaitForChild("Data"):WaitForChild("Bells").Changed:Connect(function(value)
script.Parent.TextLabel.Text = value
end)
