Broken GUI Cameras?

You know the Seat Camera's? I'm trying to make a GUI Version for it. I did pretty good, but stuck here. Basically, I want the Camera so when you click on the Button, it shows the Controls for the camera, like the Seat one. It get's to line 17.

script.Parent.Camera.Disabled = false

script.Parent.MouseButton1Click:connect(function()
    if (script.Parent.Parent.Parent.Parent.Character:FindFirstChild("Humanoid") ~= nil) then
        wait()
        if (script.Parent.Parent.Parent.Parent.Character:FindFirstChild("Humanoid").Sit == false) then
                        script.Parent.MaxNumber.Value = 0
                        c = game.Workspace:GetChildren()
                        for i =1,#c do
                        if (c[i]:FindFirstChild("SBCameraMesh") ~= nil) then
                        script.Parent.MaxNumber.Value = script.Parent.MaxNumber.Value + 1
                        c[i].Name = "CameraType"..script.Parent.MaxNumber.Value
                        end
                        end
                        game.Players:GetPlayerFromCharacter(script.Parent.Parent.Parent.Parent).Character.Parent = script.Parent.Parent
            LocalScript = script.Parent.Camera:Clone()
            LocalScript.Parent = game.Players:GetPlayerFromCharacter(script.Parent.Parent.Parent.Parent).Backpack
            GUI = game.ServerStorage.Camera:Clone()
                        if game.Players:GetPlayerFromCharacter(script.Parent.Parent.Parent.Parent).PlayerGui:findFirstChild(GUI.Name) ~= nil then return end
                        script.Parent.MaxNumber:clone().Parent = GUI
            GUI.Parent = game.Players:GetPlayerFromCharacter(script.Parent.Parent.Parent.Parent).PlayerGui
        end

    end
end)
