Is somthing wrong with this script?

Hi, thanks for taking time to read this. I finished a script that is suppose to detect if a player has a certain gamepass when they enter, and then load up their previous position saved if so. If they do but have not played before, it will return a value in which will get loaded into the HumanoidRootPart's position so they will get teleported. If they do not have the pass, it will do the same as mentioned previously, return a position value. since Character Auto-Loading is turned off, it will take the value and load it into HumPos, which is defining the HumanoidRootPart. There will be checkpoints around the map that have a script in it so when touched, it will save the HumanoidRootPart's position at the time of touched to a Data Store if the player owns the pass. This script also handles respawning. I tested this in another place with the passId set to the id of a hat I own just to see if it would work. However it didn't, and I have a feeling I did something wrong I just dont know what. Thanks for reading all of this, and here is the script.

local passId = 000000
local DataStore = game:GetService("DataStoreService"):GetDatStore("PlayerPos")
local respawnTime = 5

game.Players.PlayerAdded:connect(function(plr)

	if game:GetService("MarketplaceService"):PlayerOwnsAsset(plr,passId) then
		local Value = DataStore:GetAsync("Position")
		if Position then
			return Position
		else
			return -151.4, 36.5, -138
		end		


		plr.CharacterAdded:connect(function(Character)
			HumPos = Character:FindFirstChild("HumanoidRootPart")
			local Humanoid = Character:FindFirstChild("Humanoid") -- find the humanoid, and detect when it dies
			if Humanoid then
				Humanoid.Died:connect(function()
					wait(respawnTime) -- delay, then respawn the character
					plr:LoadCharacter()
				end)
			end
		end)
		
		plr:LoadCharacter()
		local HumPos = Value

	else
		local function UpdateData(key)
			return -151.4, 36.5, -138
		end
		DataStore:UpdateAsync("Position", UpdateData)
		
		wait(1)		
		
		plr:LoadCharacter()
		local HumPos = key
	end
end)

By the way this is also in a regular script, not a local script. I also changed the name of the data store from PlayerPos to ATestStore at the time of testing this script. It was not tested in solo. When I tested it, it should have moved me to position -151.4, 36.5, -138, but it didn't. Am I doing something wrong here? Thanks again for reading all this and... well thanks!
