How can i make a click the button then the screen open?

I have a short and simple script, this should be a Local Script located in a Text Button change GUI_NAME to the name of your GUI. And change the FRAME_NAME to the name of your Frame

local frame = script.Parent.Parent.Parent:WaitForChild('GUI_NAME').FRAME_NAME
script.Parent.MouseButton1Click:connect(function()
    frame.Visible = not frame.Visible
end)

Hope this helps!

Well, I would make a Frame in a Gui for your info and make it invisible. Then, I would make a TextButton with the following local script:

script.Parent.MouseButton1Click:connect(function()
    script.Parent.Parent.Frame.Visible=true
    script.Parent.Visible=false
end)

Put a exit button of sorts in the Frame and put a similar script in that:

script.Parent.MouseButton1Click:connect(function()
    script.Parent.Parent.Visible=false
    script.Parent.Parent.Parent.TextButton.Visible=true
end)

You can make the name of the Frame and the TextButton anything you want, just make sure you change it to that in the code. If you really know what you are doing, you could make a animation to it such as making it slowly move off the screen.
