What is wrong with my Exp Bar script?

I've got this Exp bar script that I've been working on, but it simply doesn't work. No error in the output or anything, it just doesn't run. It is in a Local Script, and I know that the Hierarchy is right as well. What is wrong here?

wait(2)

local xps = {0, 3, 6, 10, 15, 20, 25, 30, 40, 50,
    65, 80, 95, 110, 125, 140, 155, 180, 210,
    250, 300, 350, 400, 450, 500, 575, 650, 725,
    825, 1000};

function hudsize()
    local Player = game.Players.LocalPlayer
    local level = Player.leaderstats.Level.Value
    local ExpBar = script.Parent.ExpBar
    local xp = Player.Exp.Value
    local level = Player.leaderstats.Level.Value
    for level = 1, #xps do

        local required = ((xps[level] * 100)/xp)
        wait(.1)
        local size = (required * 200)
        wait(.1)
        ExpBar.Size = UDim2.new(0,15,0,size)
        print(Player.Name.."'s ExpBar Size is "..size)

        end
    end

game.Players.PlayerAdded:connect(hudsize)
game.Players.LocalPlayer.Exp.Changed:connect(hudsize)
