Problem with end) while scripting a decal spammer. Fix?

i'm making a GUI with scripts and stuff but im when scripting i always get

Expected ') ' (to close '('at line 7) got end

local DecalId = script.Parent.DecalID
local SpamButton = script.Parent.DecalButton
local SoundID = script.Parent.SoundID
local Close = script.Parent.Close


SpamButton.MouseButton1Click:connect(function()
    pingudecal = "http://www.roblox.com/asset/?id=".. DecalId.Text
    local didpingu = false
    if didpingu == false then
    didpingu = true

    if v:IsA("Player") then
    local nooties = Instance.new("Sound",workspace)
    nooties.SoundId = "http://www.roblox.com/asset/?id=".. SoundID.Text
    nooties.Volume = 1
    nooties.Looped = true
    nooties:Play()
    end
