I can't update stuff inside remoteEvent

server script(Inside Npc with button :

local rs = game:GetService("ReplicatedStorage")
local players = game:GetService("Players")

local button = script.Parent.ProximityPrompt
local event = rs.Remotes:WaitForChild('RemoteDialogText') 


local Quest = 60



local DialogsData = {


	nic0 = {"Helo can you do something for me ? ", "I lost my sponge, can you fint this ?"," did you find my sponge? " },
	nic0Answers = {No="No",Yes = "Okey",MaxStrony = 3, NextQuest ="NpcKIll",ThingsUneed ="Sponge",EndText =" thanks, you found my sponge",xp=80 }, -- just some data 
	
	NpcKIll0 = {"Test combat for me","get back to work"},
	NpcKIll0Answers = {No="No",Yes = "Okey",MaxStrony = 1, NextQuest ="NpcKIll",ThingsUneed ="",NpcToKIll="Tester",NpcToKIllNum=1,EndText =" thanks",xp=200 }, -- just some data
	
	text60 ="No DAta"
}




button.Triggered:Connect(function(Plr)

	local player = players:FindFirstChild(Plr.Name)
	local PLbacpack = Plr.Backpack
	local idk = Plr.Character
	local Quests = idk.QuestsStatus

	local lvl = Quests:GetAttribute("Status")

	print(name..lvl)
	


	local Slowa = DialogsData[name..lvl]
	local Answers = DialogsData[name..lvl.."Answers"]
	
	

		event:FireClient(player,Answers ,Slowa,PLbacpack)
	
	
	
end)

local script(inside gui) :

local character = game:GetService("Players").LocalPlayer.Character

end)



server script (Inside character Scripts) :

local event = rs.Remotes.RemoteEventNextQuest
local eventNpcKIllName = rs.Remotes.RemoteEventKIllNpcName
event.OnServerEvent:Connect(function(plr,NextQuest)
	
	local Quest = NextQuest
	
	script:SetAttribute("Name",Quest)
	
	
end)

eventNpcKIllName.OnServerEvent:Connect(function(plr,Model)
	
	print("jkahdjkasjkda")
	
end)


--while true do 
--	wait(3)
--	print(script:GetAttribute("Name").." lvl "..script:GetAttribute("Status"))
	
--end

Problem:

error inside local script :

Then the game start and I activate the button everything work great.(I pick up the sponge and click on npc)
But when I end first quest and the “RemoteDialogText” updates, then everything in “RemoteDialogText” changes to nil.
