What is wrong with my script?

I dont know what I'm doing wrong, what is wrong with it? The script it meant to make sure the rank Colonel in my group and greater can do those commands.

assert(workspace:FindFirstChild("Generator")~=nil,"There is no Generator model!")

gs = {} 

trainers = {"Moosee",""}

function globalScript(s)
yes = false
    for i = 1,#gs do
        if s.Name == gs[i] then
        yes = true
        break
        end
    end
return yes
end

game.Players.PlayerAdded:connect(function(player)
    if player:GetRankInGroup(1126064) >= 13 then 
        trainers[#trainers+1] = player.Name
    end
    for i=1,#trainers do
        if trainers[i]==player.Name then
        player.Chatted:connect(onDoorSpeak)
        break
        end
    end
end)

    for _,v in pairs(workspace:GetChildren()) do

    end
