I made a script that saves the data of the player and its not working? Script:

local Data = game:GetService('DataStoreService'):GetDataStore('SaveDem')
	 
	local prefix = 'user_'
	 
	 
	game.Players.PlayerAdded:Connect(function(player)
	    local folder = Instance.new('Folder')
	    folder.Name = 'leaderstats'	 
	    local CaseBux = Instance.new('IntValue',folder)
	    CaseBux.Name = 'Crate Bux'
	
	
        local IsCode1Used = Instance.new('BoolValue', folder)
        IsCode1Used.Name = "IsCode1Used"


        local IsCode2Used = Instance.new('BoolValue', folder)
        IsCode2Used.Name = "IsCode2Used"

	 
	    local RAP = Instance.new('IntValue',folder)
	    RAP.Name = 'RAP'	 
	    local plrData = Data:GetAsync(prefix  .. tostring(player.UserId))
	 
	    if plrData then
	          CaseBux.Value = plrData[0] or 0
	          RAP.Value = plrData[1] or 0
	          IsCode1Used.Value = plrData[2] or false 
	          IsCode2Used.Value = plrData[3] or false
	           
	          
	   else
	 
	    Data:SetAsync(prefix  .. tostring(player.UserId), {
	        CaseBux.Value,
	        RAP.Value,
			IsCode1Used.Value,
			IsCode2Used.Value
	     })
	   end
	 
	end)
	 
	game.Players.PlayerRemoving:Connect(function(player)
	    Data:SetAsync(prefix  .. tostring(player.UserId), {
	        player.leaderstats.CaseBux.Value,
	        player.leaderstats.RAP.Value,
			player.leaderstats.IsCode1Used.Value,
			player.leaderstats.IsCode2Used.Value
	    })
	end)
