Why does my Playerlist dont work ? It don´t show the players.

So I have it in StarterGui The terms in quotation marks are the objects. The above are the names

? Playerlist
      localScript "localScript
    ? Frame "Frame"
         slots "Folder"
        ? TextLabel "Frame"
            ImageLabel "ImageLabel"
            ImageLabel "ImageLabel"
            TextLabel "TextLabel"
        Template "TextLabel"

That´s my Script:

--< variables

local players = game:GetService("Players")
local frame = script.Parent.Frame
local slots = frame.slots
local temp = frame.Template

local players_table = {}

--< tween info:TweenPosition(endPosition, EasingDirection, EasingStyle, Time, Override)

local dir = "Out"
local style = "Quad"
local dur = 0.5

--< functions

local function cleanup(slot)

    -- repeat wait until the slot finishes tweening
    repeat
        wait()
    until slot.Position.X.Offset == 400
    slot:Destroy()

end

local function remove(leaving)

    -- check if a player is leaving
    if leaving then

        -- if so, delete dictionary entry 
        players_table[leaving] = nil
        -- tween player slot out
        local slot = slots:FindFirstChild(leaving)
        slot:TweenPosition(UDim2.new(0, 400, 0, slot.Position.Y.Offset), dir, style, dur, true)

        -- delete the slot once it finishes (coroutine)
        local cor = coroutine.wrap(cleanup)
        cor(slot)

    end
end

local function add()

    -- loop through players
    local chil = players:GetChildren()
    for c = 1, #chil do

        -- check if present in dictionary
        if players_table[chil[c].Name] == nil then

            -- add to dictionary
            players_table[chil[c].Name] = 1

            -- create a slot in the list
            local slot = temp:Clone()

                -- edit that slot
                slot.Name = chil[c].Name
                slot.Text = slot.Name
                slot.Parent = slots
        end
    end
end

local function adjust(leaving)

    -- add() and remove()
    add()
    remove(leaving)

    local count = 0
    -- loop through players_table
    for key, value in pairs(players_table) do
    count = count + 1
        -- find corresponding slots
        local slot = slots:FindFirstChild(key)

        -- tween slot positions
        local ypos = 30 + (25+2)*(count-1)  
        slot:TweenPosition(UDim2.new(0, 0, 0, ypos), dir, style, dur, true)

    end         
end

--< events

-- player added event
players.PlayerAdded:connect(function()
    adjust(nil)
end)

-- player removing event
players.PlayerRemoving:connect(function(leaving)
    adjust(leaving.Name)
end)

--< setup

adjust()
