Why is my stage value not showing up in leaderstats?

[sudden socket]

I have no error message in output and the stages are being saved since they show up in the PlayerData folder.. so why won't it display on the leaderstats?

here's the script:

local PlayerDataFolder = serverStorage:WaitForChild("PlayerData")
local Spawns = game.Workspace:WaitForChild("Checkpoints")

game.Players.PlayerAdded:Connect(function(player)
    player.RespawnLocation = game.Workspace.Checkpoints["0"]
    
    local playerFolder = Instance.new("Folder")
    playerFolder.Name = player.UserId
    playerFolder.Parent = PlayerDataFolder
    
    local currentStage = Instance.new("IntValue")
    currentStage.Name = "Stage"
    currentStage.Value = 0
    currentStage.Parent = playerFolder
    ------------------------------------------------
    local leaderstats = Instance.new("Folder")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player
    
    local stageDisplay = Instance.new("IntValue")
    stageDisplay.Name = "Stages"
    stageDisplay.Value = currentStage.Value 
    stageDisplay.Parent = leaderstats
end)

for i, v in pairs(Spawns:GetChildren()) do
        v.Touched:Connect(function(otherpart)
            if otherpart.Parent:FindFirstChild("Humanoid") then
                local player = game.Players:GetPlayerFromCharacter(otherpart.Parent)
                local playerFolder = PlayerDataFolder:FindFirstChild(player.UserId)
                local currentStage = playerFolder:WaitForChild("Stage")
                local spawnStage = tonumber(v.Name)
                if (spawnStage == currentStage.Value + 1) then
                    currentStage.Value = currentStage.Value + 1
                    player.RespawnLocation = v
                end
            end
        end)
    end```

its because your not updating the value of stageDisplay.Value your only updating currentStage.Value

My solution creates main table called playerTbl. When a player joins, I insert their UserId into the table, and assign it a nested subtable. Inside that nested table, I store a key named stageDisplay, whose value is the actual IntValue object named "stageDisplay" in leaderstats.

if (spawnStage == currentStage.Value + 1) then
      currentStage.Value = spawnStage
      playerTbl[uid]['stageDisplay'].Value = spawnStage
      player.RespawnLocation = spawn
end
