Im having trouble with a localscript to hide a gui?fffffffffffffffffffffffffffff

So i made a gui and want to add a Show/Hide button because its very big and takes up much of the screen. What i tried is making a new textbutton and making a localscript inside of it with following content:

script.Parent.MouseButton1Click:Connect(function()
	
game.StarterGui.FGHUB.MainFrame.Visible = false
game.StarterGui.FGHUB.UpperLine.Visible = false
game.StarterGui.FGHUB.DownLine.Visible = false
game.StarterGui.FGHUB.LeftLine.Visible = false
game.StarterGui.FGHUB.RightLine.Visible = false
game.StarterGui.FGHUB.Login.Visible = false
game.StarterGui.FGHUB.Password.Visible = false
game.StarterGui.FGHUB.Username.Visible = false
game.StarterGui.FGHUB.FGHub.Visible = false
	
		
	
end)

altough the frames dont turn invisible And i dont know what to do

Help would be appreciated

This wont work because your taking the StarterGui, You need to take the Player's PlayerGui.

READ THIS: If you want it to not only hide and also show, I prefer you use the last script. If you want it to only hide, I prefer you use the 3rd script.

Here is the fixed script:

local Player = game.Players.LocalPlayer -- Gets the player
local PlayerGui = Player:WaitForChild("PlayerGui") -- Gets the player's PlayerGui/Guis
local FGHUB = PlayerGui.FGHUB -- To make it more nicer, Gets the FGHUB Gui

script.Parent.MouseButton1Click:Connect(function()
	FGHUB.MainFrame.Visible = false
	FGHUB.UpperLine.Visible = false
	FGHUB.DownLine.Visible = false
	FGHUB.LeftLine.Visible = false
	FGHUB.RightLine.Visible = false
	FGHUB.Login.Visible = false
	FGHUB.Password.Visible = false
	FGHUB.Username.Visible = false
	FGHUB.FGHub.Visible = false
end)

If you want it to not only hide and also show use this script:

local Player = game.Players.LocalPlayer -- Gets the player
local PlayerGui = Player:WaitForChild("PlayerGui") -- Gets the player's PlayerGui/Guis
local FGHUB = PlayerGui.FGHUB -- To make it more nicer, Gets the FGHUB Gui

script.Parent.MouseButton1Click:Connect(function()
	if FGHUB.MainFrame.Visible == true then -- Checks if it's visible
		FGHUB.MainFrame.Visible = false
		FGHUB.UpperLine.Visible = false
		FGHUB.DownLine.Visible = false
		FGHUB.LeftLine.Visible = false
		FGHUB.RightLine.Visible = false
		FGHUB.Login.Visible = false
		FGHUB.Password.Visible = false
		FGHUB.Username.Visible = false
		FGHUB.FGHub.Visible = false
	else -- Checks if it's not visible/invisible
		FGHUB.MainFrame.Visible = true
		FGHUB.UpperLine.Visible = true
		FGHUB.DownLine.Visible = true
		FGHUB.LeftLine.Visible = true
		FGHUB.RightLine.Visible = true
		FGHUB.Login.Visible = true
		FGHUB.Password.Visible = true
		FGHUB.Username.Visible = true
		FGHUB.FGHub.Visible = true
	end
end)

If you want it more nicer, Organized and shorter use this script:

local Player = game.Players.LocalPlayer -- Gets the player
local PlayerGui = Player:WaitForChild("PlayerGui") -- Gets the player's PlayerGui/Guis
local FGHUB = PlayerGui.FGHUB -- To make it more nicer, Gets the FGHUB Gui

script.Parent.MouseButton1Click:Connect(function()
	FGHUB.Enabled = false
end)

If you want it more nicer, Organized, Shorter and you want it to not only hide it and also show use this script:

local Player = game.Players.LocalPlayer -- Gets the player
local PlayerGui = Player:WaitForChild("PlayerGui") -- Gets the player's PlayerGui/Guis
local FGHUB = PlayerGui.FGHUB -- To make it more nicer, Gets the FGHUB Gui

script.Parent.MouseButton1Click:Connect(function()
	if FGHUB.Enabled == true then -- Checks if it's visible
		FGHUB.Enabled = false
	else -- Checks if it's not visible/invisible
		FGHUB.Enabled = true
	end
end)

If this helped you please accept my answer that would be really appreciated.
