Works in studio but not in game?

I have 2 scripts that work in studio but not in the real game. Why is this? And can someone fix them so they work in game?

script.Parent.MouseButton1Down:connect(function()
	if script.Parent.Parent.Parent.Value.Value == 0 then
	local g = Instance.new("BillboardGui")
	g.Parent = script.Parent.Parent.Parent.Parent.Parent.Character.Head
	g.Size = UDim2.new(4,0,2,0)
	g.Name = "Q"
	local t = Instance.new("TextBox")
	t.Parent = script.Parent.Parent.Parent.Parent.Parent.Character.Head.Q
	t.Text = "Question"
	t.BackgroundTransparency = 1
	t.TextColor3 = Color3.new(0/255, 170/255, 0/255)
	t.FontSize = "Size12"
	t.Size = UDim2.new(1,0,1,0)
	g.StudsOffset = Vector3.new(0, 3, 0)
	script.Parent.Parent.Parent.Value.Value = 1
	else
		script.Parent.Parent.Parent.Value.Value = 0
		script.Parent.Parent.Parent.Parent.Parent.Character.Head.Q.TextBox:Remove()
		script.Parent.Parent.Parent.Parent.Parent.Character.Head.Q:Remove()
		
	end
	end)

script.Parent.MouseButton1Down:connect(function() script.Parent.Parent.Parent.Parent.Parent.Character.Torso:Destroy() end)
