This script isnt changing the player's values, why not?

I am making a save script that saves a list of booleans. I am trying to save whether someone has a perk or not, and when I try and load the saves it says

"ServerScriptService.SavePerks:21: attempt to index nil with number". Below is the script I'm working with. -Solved

For some reason, the script isn't changing the player's values. I don't see any errors, but I'm new to scripting so maybe one of you guys might. Also, when I leave the game, it says there is an error while trying to save the data. There is no error code or message it just warns that "There was an error while loading data! Errormessage:".

local DataStoreService = game:GetService("DataStoreService")
local List = DataStoreService:GetDataStore("List")
local PerkList = {"CammoBottle", "Crocodile", "Poo"}
local PerkStatus = {true, true, false}
local Temp = {}
-- true means it is defaulted to on. false means it is defaulted to off.
-- Values will change depending on what a person has saved

game.Players.PlayerAdded:Connect(function(plr)
	local Data
	local success, errormessage = pcall(function()
		Data = List:GetAsync(plr.UserId.."-List2")
	end)
	
	if success then
		wait(0.1)
		for _, e in pairs(plr.Values.Perks:GetChildren()) do
			for i, e2 in ipairs(PerkList) do
				print(e.Name..", "..e2)
				if e.Name  == e2 then
					e.Value = Data[i]
					print(e.Name..", "..Data[i])
				end
			end
		end
		print("Perk Data Loaded")
	else
		warn("There was an error while loading data! Errormessage:")
		warn(errormessage)
		warn("Defaulting Perks")
		for _, e in pairs(plr.Values.Perks:GetChildren()) do
			for i, e2 in ipairs(PerkList) do
				if e.Name  == e2 then
					e.Value = PerkStatus[i]
				end
			end
		end
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	local success, errormessage = pcall(function()
		for _, e in pairs(plr.Values.Perks:GetChildren()) do
			for i, e2 in ipairs(PerkList) do
				if e.Name  == e2 then
					table.insert(Temp, i, e2[i])
				end
			end
		end
		List:UdateAsync(plr.UserId.."-List2", Temp)
	end)
	
	if success then
		print("Data Saved")
	else
		warn("There was an error when saving data! Errormessage:")
		wait(errormessage)
	end
	
end)

This is what the game.Players[player].Values folder is: Click to view

This is not extremely important but if I want to add more perks to my game this will make it easier.
