Expected identifier when parsing expression, got ')'??

So, you're literally missing an end at the bottom.

So it would be like this:

local TeleportService = game:GetService ("TeleportService")
local part = script.Parent
local debounce

debounce = false

    part.Touched:Connect (function(hit)

        if debounce == false then
        debounce = true

    local human = hit.Parent:FindFirstChild("Humanoid")


        if human then
            local char = hit.Parent


        local player = game.Players:GetPlayerFromCharacter(char)
            TeleportService:Teleport(gameID, player)

    wait(5)
    debounce = false

        end
        end
end)

Don't need to copy and paste of course, just write down the extra end :/
