Why wont this show a Gui? (closed)

First of all, you really don't want to adjust the GUIs in the StarterGui, because that is a service that gives a copy of the GUI to the players' PlayerGui, therefore the change won't be visible right away.

What the code should be accessing is the players' PlayerGui, because that's where the players' real-time displayed GUIs are stored.

-- Since I'm using LocalPlayer, this MUST be in a LocalScript.
-- Since this is supposed to be in a LocalScript, a :WaitForChild() method is recommended to utilize.

local GUI = game.Players.LocalPlayer.PlayerGui:WaitForChild("ScreenGui")
local button = GUI:WaitForChild("Help")
button.MouseButton1Click:connect(function()
    game.Players.LocalPlayer.PlayerGui.Info.Information.Active= true
end)

-- For this function, put your connection line OUTSIDE; otherwise the function won't fire if the connection line is within an 'unfired' function.

local function clicked()
    game.Players.LocalPlayer.PlayerGui.Info.TextBox.Visible=true
    wait(10)
    game.Players.LocalPlayer.PlayerGui.Info.TextBox.Visible=false
end
game.Players.LocalPlayer.PlayerGui.ScreenGui.TextButton.MouseButton1Click:connect(clicked)

If your script is within one of the GUIs, then I recommend referring your GUI objects starting from the script (such as script.Parent).

EXAMPLE

Let's assume your script is within ScreenGui. You don't necessarily have to have a LocalScript this way. You could use script.Parent.Parent.Info to access the Info GUI.

local GUI = script.Parent
local button = GUI:WaitForChild("Help")
local InfoGui = GUI.Parent:WaitForChild("Info")
button.MouseButton1Click:connect(function()
    InfoGui.Information.Active= true
end)

local GUI = script.Parent
local TB = GUI:WaitForChild("TextButton")
local InfoGui = GUI.Parent:WaitForChild("Info")

local function clicked()
    InfoGui.TextBox.Visible=true
    wait(10)
    InfoGui.TextBox.Visible=false
end

TB.MouseButton1Click:connect(clicked)
-- NOTE: You don't have to have a plethora of variables with a :WaitForChild() method, especially if the script is server-sided.
--But it's a habit for me because I'm quite meticulous when it comes to scripting, as I want to avoid as much errors as possible.

script.Parent.MouseButton1Click:connect(function()

game.StarterGui.TextButton.Visible = true

end)

script.Parent.MouseButton1Click:connect(function()

script.Parent.Parent.VISIBLEME.Visible= true

end)

You need to tell it where you want it to click

Put the script inside the button you want to become visible

EDIT: Make a button and make the button name that you want to be visible be called VISIBLEME

If it does then go to the wiki and learn more basics.
