How do you remove and add a GUI with the use of a Button?

So, I made a button, and what i want it to do is there is a GUI on screen, and i want it that if you press the button, it hides the GUI on screen, and replaces it with another one. Like you start off with a GUI on screen that says something like 'Hello', and then when you press the button, the GUI changes and then the GUI says 'How are you?' (As an example)

Edit: I dont want to make a new GUI, like i made the two GUI's, i just need them to like switch places when you press a button. Like you start off with one, which has already some buttons and stuff in, but when you press a button, the first GUI disappears, and the second one appears. Then you press the button again, and you get the first GUI again.

Please help me out! I've tried everything I could think of!

You don't have to change whole gui you can just change the text of TextLabel inside of it

local Player = game.Players.LocalPlayer
local Label = Player.PlayerGui:WaitForChild("ScreenGui").TextLabel
ExampleButton.MouseButton1Click:Connect(function()
       Label.Text = "How are you?"
end)

Note: This will not be formated very well because I am ob phone

I'm thinking your wanting to make a dialog type thingy.

You may want to look into using tables to accomplish this...maybe something like this(did not test)

local textTable = {'Hi, John';'How are you today?';'Lolz don't care'}

local key = 1

script.Parent.MouseButton1Click:Connect(function()
	script.Parent.TextLabel.Text = textTable[key]
	key = key + 1
end)

Something along those lines :)

if your wanting the textbox to disapear then use transparency or look into TweenPosition and such.

button1.MouseButton1Click:connect(function()
	GUI1.transparency = 1
	GUI2.transparency = 0
end)
button2.MouseButton1Click:connect(function()
	GUI1.transparency = 0
	GUI2.transparency = 1
end)

It should work like this!
