Event Firing Repeatedly? Meant to fire each time u reach a new level.

function LevelNotify(lvl)
	Player.PlayerGui.LevelNotify.LevelUp:Fire(lvl)
end
function onLevelUp(lvl)
	LVL_HUE = math.clamp(tonumber(lvl), 1, 100) / 100 * 0.8333333333333334
	Info.XP.Bar.Level.Text = "LEVEL " .. lvl
	Info.XP.Bar.BackgroundColor3 = Color3.fromHSV(LVL_HUE, 1, 0.19607843137254902)
	Info.XP.Bar.Fill.BackgroundColor3 = Color3.fromHSV(LVL_HUE, 1, 1)
end
Database.Notify.OnClientEvent:connect(function(action, ...)
	local vars = {
		...
	}
	if action == "new tp" then
		onPointsAdded(vars[1])
	elseif action == "new level" then
		onLevelUp(vars[1])
		LevelNotify(vars[1])
	elseif action == "new xp" then
		onXPChange(vars[1])
	end
end)
onLevelUp(sendControl("get level"))
onPointsAdded(sendControl("get tp"))
onXPChange(sendControl("get xp"))

Im trying to make it so it doesnt loop, it only does the lvlnotify fire each time ur at a new level.

I dont know whats wrong with your script would need more info but this is what i use and its much much better, you can change the xpp required whenever and ittl auto update for the players. the function should be in a module returns a table and you can get the data by doing tbl[1] or tbl[2] or tbl[3] from the returned side

module.get_rank = function(name)
	local wins = --Players wins
	local req = module.start_wins
	local inc = module.wins_increase
	local rank = 0
	repeat
		if wins >= req then
			wins = wins - req
			req = req + inc
			rank = rank + 1
		end
	until wins < req
	local tbl = {rank, wins, req}
	return tbl
end
