Help with DataStore/other?

My DataStore and leaderboard worked perfectly before, except now I added two new IntValues -- ExperienceNeeded(inside Experience value in leaderboard) and MaxLevel (inside Level value in leaderboard). I have attempted to make a system that lets players level up and gain money based on how many points they have. I am getting these errors:

22:33:52.708 - Experience is not a valid member of IntValue 22:33:52.709 - Script 'Workspace.lvlDealer', Line 3 22:33:52.709 - Stack End

22:35:24.233 - Can't parse response 22:35:24.235 - Script 'Workspace.Leaderboard', Line 53 22:35:24.235 - Stack End

(I've put comments on the lines which have errors on them for convenience.)

Leaderboard script:

local levl = game:GetService('DataStoreService'):GetDataStore('Level') 
local EXP = game:GetService('DataStoreService'):GetDataStore('Experience')
local mon = game:GetService('DataStoreService'):GetDataStore('Money')
local pnts = game:GetService('DataStoreService'):GetDataStore('Points')
local expn = game:GetService('DataStoreService'):GetDataStore('ExperienceNeeded')

function load1(plr)  --loads players credits
    return levl:GetAsync(plr.userId) or levl:SetAsync(plr.userId, 1) and 0
end

function load2(plr)  --loads exp function will either set or gets them from last time
    return EXP:GetAsync(plr.userId) or EXP:SetAsync(plr.userId, 0) and 0
end

function load3(plr)  --loads exp function will either set or gets them from last time
    return mon:GetAsync(plr.userId) or mon:SetAsync(plr.userId, 0) and 0
end

function load4(plr)  --loads exp function will either set or gets them from last time
    return pnts:GetAsync(plr.userId) or pnts:SetAsync(plr.userId, 0) and 0
end

function load5(plr)
	return expn:GetAsync(plr.userId) or expn:SetAsync(plr.userId, 83) and 0
end


game.Players.PlayerAdded:connect(function(plr)  --player joins
	local ls = Instance.new("IntValue",plr)
	ls.Name = "leaderstats"
    local lvl = Instance.new('IntValue', ls)
    lvl.Name = 'Level' 
    lvl.Value = load1(plr)
	local ml = Instance.new("IntValue", plr)
	ml.Name = "MaxLevel"						--changes the value from the load function
	ml.Value = 99
    local xp = Instance.new('IntValue', ls)
    xp.Name = 'Experience'
    xp.Value = load2(plr)
	local en = Instance.new("IntValue", xp)
	en.Name = "ExperienceNeeded"
	en.Value = load5(plr)
	local money = Instance.new("IntValue", ls)
	money.Name = 'Money'
	money.Value = load3(plr)
	local points = Instance.new("IntValue", ls)
	points.Name = 'Points'  --changes the value from the load function
	points.Value = load4(plr)
	while true do
		wait(5)
		levl:UpdateAsync(plr.userId, function() return plr.leaderstats.Level.Value end)
   		EXP:UpdateAsync(plr.userId, function() return plr.leaderstats.Experience.Value end)
   	 	mon:UpdateAsync(plr.userId, function() return plr.leaderstats.Money.Value end)
   	 	pnts:UpdateAsync(plr.userId, function() return plr.leaderstats.Points.Value end)
		expn:UpdateAsync(plr.userId, function() return plr.leaderstats.Experience.ExperienceNeeded.Value end)
	end
end)

game.Players.PlayerRemoving:connect(function(plr)  --saves it when player leaves
    levl:UpdateAsync(plr.userId, function() return plr.leaderstats.Level.Value end)
    EXP:UpdateAsync(plr.userId, function() return plr.leaderstats.Experience.Value end)
    mon:UpdateAsync(plr.userId, function() return plr.leaderstats.Money.Value end)
    pnts:UpdateAsync(plr.userId, function() return plr.leaderstats.Points.Value end)
	expn:UpdateAsync(plr.userId, function() return plr.leaderstats.Experience.ExperienceNeeded.Value end)
end)

dealer script (gives experience and money based on how many points you earned during a round):

local gt = game.Workspace.gameRunner.gameTime
local Debounce = false
game.Players.PlayerAdded:connect(function(plr)
	wait(1)
	local p = plr.leaderstats.Points.Value
	local m = plr.leaderstats.Money.Value
	local e = plr.leaderstats.Experience.Value
	if gt.Value == 1 and Debounce == false then
		Debounce = true
		m = m + p/2
		e = e +p
		p = p - p
		wait(1)
		Debounce = false
	end
end)

lvldealer script (awards a level when the exp = expneeded, and makes it so you cant go above level 99):

game.Players.PlayerAdded:connect(function(plr)
	wait(1)
	local e = plr.leaderstats.Experience.Value
	local l = plr.leaderstats.Level.Value
	local ml = plr.MaxLevel.Value
	local en = plr.Experience.ExperienceNeeded.Value
	
	if e == en then
		l = l+1
		e = e - en
		en = en*1.10409
	end
	if l == ml then
		en = nil
	end
end)

I know there's a lot of code here, but it would mean so much to me if somebody could fix this. I don't know what to do. Thank you :)
