how to add experience value every 5 sec?

game.Players.PlayerAdded:connect(function(plr)
	local stats = Instance.new('IntValue', plr)
	stats.Name = 'leaderstats'
	
	local experience = Instance.new('IntValue', stats)
	experience.Name = 'EXP'
	experience.Value = 0
	
	local level = Instance.new('IntValue', stats)
	level.Name = 'level'
	level.Value = 0
	
	experience.Changed:connect(function()
	   level.Value = math.floor(experience.value / 1000)
		
	
	end)
	
end)



local player = game.Players.LocalPlayer
local leaderstats = player:WaitForChild('leaderstats')
local level = leaderstats:WaitForChild('level')
local xp = player:WaitForChild('exp')

level.Changed:connect(function()
	if xp.Value < 1000 then
		level.Value = 1
		
     end
end)

i tried really hard to make this but i don't know how to continue, i wanted it to give 100 'experience' every 5 seconds. thanks in advanced

Line 14 experience.value should be experience.Value
