Why is the intValue in only one player working?

I have my game set up so that all players get stringValues inside of them with the value "Linked", and for some reason whenever I do local servers or play with my friend on the server, only one character has the value "Linked." Why isn't this working?

local DataStore = game:GetService("DataStoreService"):GetDataStore("DataStorage")


--[[function TweenIncentive()
	for i, v in pairs(game.Players:GetPlayers()) do
		v.PlayerGui.PlayerScreenGui.LogInReward:TweenPosition(0, 600, 0, 0)
		wait(3)
		v.PlayerGui.PlayerScreenGui.LogInReward:TweenPosition(0, 2000, 0, 0)
		v.PlayerGui.PlayerScreenGui.LogInReward.Position = UDim2.new(0, -100, 0, 0)
	end
end]]

I noticed that you tried to put a string inside a number value on line forty:

local level = Instance.new("NumberValue", stats)
level.Name = "Level"
level.Value = "Linked"

also the second parameter of Instance.new is deprecated. You should set the parent like so:

local level = Instance.new("NumberValue")
level.Parent = stats
level.Name = "Level"
