Leaderboard not updating/saving values?

I am trying to make a script to save a value called "Reputation" and update the datastores when a player gets the increase (like at the end of a round) or when they're leaving. I used a block to test this out by giving me 10 Rep every time I touch it and it worked at first but the value wouldn't save. All the code 'checkpoints,' if you will, gave me success messages but the values still don't save. I have tried rewriting it several times and I have searched for examples to go off of and I cannot seem to get it to work. I was trying to get it to index a player with a value of 1 if they didn't exist but this is proving to be rather tricky. I even watch the value of the IntValue stay at 0 even though the code shows it at 10 when using a breakpoint. I think I might just not be finding the correct value for reputation but I figured I could still submit it here to see if I could save some time. Below is my code for the leaderboard:

--Datastore--
local Datastore = game:GetService("DataStoreService") --gets service
local GameStatStorage = Datastore:GetDataStore("gamestats") --creates a link to use for accessing the datastore


game.Players.PlayerAdded:Connect(function(plr) --when a player joins
	local folder = Instance.new("Folder")  --Makes folder for stats
	folder.Parent = plr --places it 
	folder.Name = "leaderstats" --names it
	local reputation = Instance.new("IntValue") -- makes a place to store the value of the players reputaion
	reputation.Parent = folder --places the value container
	reputation.Name = "Reputation"
	local success, err = pcall(function() --wraps in pcall
		GameStatStorage:GetAsync(plr.UserId.."-Reputation") --gets the players data
	end)
	if success then --if good then 
		print "Successfully Loaded" --Success message
		plr.leaderstats.Reputation.Value = success --sets visible value to match
	else --or if player doesnt have data to pull
		plr.leaderstats.Reputation.Value = 1 -- then give them a value of zero to display
		GameStatStorage:SetAsync(plr.UserId, 1) --submit the number to the datastore server
		print "Player Data not found. Err201"
		warn "Err201 - Value created and set to 1"
	end	
	
end)

game.Players.PlayerRemoving:Connect(function(plr) --when player is leaving
	
	local function valueOfRep()
		return plr.leaderstats.Reputation.Value
	end
	
	local success, err = pcall(function() --wrap in pcall
		GameStatStorage:UpdateAsync(plr.UserId.."-Reputation", valueOfRep) --saves value the person has
	end)
	if success then
		print "Save to leave Successful"
	else
			print("Error in saving to leave")
			warn(err)
	end
end)
