trying to make it you get level one at 1000 xp and at 2257 xp you get level 2 anything less then 1000 xp is level 0 btw

local level = game:GetService("DataStoreService"):GetDataStore("Levels")
local Xp = game:GetService("DataStoreService"):GetDataStore("Xp")
local axp = game:GetService("DataStoreService"):GetDataStore("AXP")
local RequiredXP = {
    [0] = 1000,
    [1] = 2257
}

function savedata(dataname, playerid)
    game:GetService("DataStoreService"):GetDataStore(dataname):SetAsync(playerid, Value)

end

game.Players.PlayerAdded:connect(function(player)
    local leader = Instance.new("Folder")
    leader.Name = "leaderstats"
    leader.Parent = player
    local levels = Instance.new("IntValue")
    levels.Value = level:GetAsync(tostring(player.userId)) or 1
    levels.Name = "Level"
    levels.Parent = player:WaitForChild("leaderstats")
    local Xpz = Instance.new("NumberValue")
    Xpz.Value = Xp:GetAsync(tostring(player.userId))
    Xpz.Name = "Xp"
    Xpz.Parent = player
    local xpn = Instance.new("IntValue")
    xpn.Value = axp:GetAsync(tostring(player.userId))or 1000
    xpn.Name = "XpNeeded"
    xpn.Parent = player

    Xpz.Changed:connect(function()
    if player:WaitForChild("Xp").Value >= player:WaitForChild("XpNeeded").Value then
        levels.Value = levels.Value+1
        xpn.Value = RequiredXP[levels.Value]
        savedata("levels",player.userId.levels.Value)
        savedata("Xp",player.userId.Axp.Value)
        savedata("Axp",player.userId.xpn.Value)

    else
        savedata("levels",player.userId.levels.Value)
        savedata("Xp",player.userId.Axp.Value)
        savedata("Axp",player.userId.xpn.Value)

    end
end)
end)
