My admin tablets don't work?

Okay, this is another long job. My tabs never load into workspace? Why does this happen?

tabs = {}
tabSettings = {
    size = Vector3.new(4,4,4),
    material = Enum.Material.Neon,
    anchored = true,
    locked = true
}
tabs = {}
Output = function(Player,Text,Color)
    if not game.Players:FindFirstChild(Player) then return else Player = game.Players:FindFirstChild(Player); end;
    if Text == nil then Text = "Sample text"; end;
    if Color == nil then Color = BrickColor.new("Really red");
    local tab = Instance.new("Part",workspace);
    tab.Anchored = tabSettings.anchored;
    tab.Locked = tabSettings.locked;
    tab.Size = tabSettings.size;
    tab.Material = tabSettings.material;
    tab.TopSurface,tab.BottomSurface = 0,0;
    tab.FormFactor = "Custom";
    local sb = Instance.new("SelectionBox",tab);
    sb.Adornee = tab;
    sb.Color = BrickColor.new(Color).Color;
    sb.Transparency = .2;
    sb.LineThickness = .03;
    local gui = Instance.new("BillboardGui",tab);
    gui.Adornee = tab;
    gui.Size = UDim2.new(1,0,1,0);
    gui.StudsOffset = Vector3.new(0,2.5,0);
    local tl = Instance.new("TextLabel",gui);
    tl.Text = Text;
    tl.Size = UDim2.new(1,0,1,0);
    tl.TextColor3 = tab.Color;
    tl.BackgroundTransparency = 1;
    tl.Font = "Arial";
    tl.FontSize = "Size18";
    tl.TextStrokeTransparency = .81
    tl.TextStrokeColor3 = Color3.new(255,255,255);
    tl.TextTransparency = 0;
    local cd = Instance.new("ClickDetector",tab);
    cd.MaxActivationDistance = 1000;
    cd.MouseClick:connect(function(p)
        if p.Name == Player.Name then
            tab:Destroy();
            for i,v in pairs(tabs) do
                if v.Name == tab.Name then
                    table.remove(tabs,i)
                end
            end
        end
    end)
    tab.Parent = workspace;
    pcall(function()
        tab.CFrame = Player.Character.Torso.CFrame;
    end)
    table.insert(tabs,{Tab = tab,Player = Player,Text = tl, Sb = sb});
    end
end
Output("28nard","This is some text","Really red")

there aren't any errors...
