A Script That Runs In Studio But Not On Roblox Servers Can Someone Help Me Fix This Script?

I Am Working A Roblox RPG Game And I Have A Script That Works In Roblox Studio But Not In The Normal Roblox Server. Can Someone Fix This I Have No Clue What Is Wrong With It.(By The Way It Is A Script Not A Local Script Encase That Has To Do With The Problem)

Here Is The Script

player = game.Players.LocalPlayer

local Enabled = false

function UpdateInventory() if Enabled == false then Enabled = true script.Parent.Frame.Visible = true script.Parent.Frame.CanvasSize = UDim2.new(0,0,0,20#player.Backpack:children()) script.Parent.Frame:ClearAllChildren() for i,v in pairs(player.Backpack:GetChildren()) do Obj1 = Instance.new('TextButton',script.Parent.Frame) Obj1.Size = UDim2.new(1,-12,0,20) Obj1.Position = UDim2.new(0,0,0,20i-20) Obj1.BackgroundTransparency = 1 Obj1.FontSize = 'Size24' Obj1.Text = v.Name Obj1.Font = 'SourceSansBold' Obj1.TextColor3 = Color3.new(255,255,255) Obj1.TextXAlignment = 'Left' Obj1.MouseButton1Down:connect(function() player.Character.Humanoid:UnequipTools() player.Character.Humanoid:EquipTool(v) end) end else Enabled = false script.Parent.Frame.Visible = false end end

script.Parent.InvenButton.MouseButton1Down:connect(function() UpdateInventory() end)

player.Backpack.Changed:connect(function() if Enabled == false then Enabled = true UpdateInventory() end if Enabled == true then Enabled = false UpdateInventory() end end)
