how would i make a button to remove my welcome Gui?

so i made a welcome GUi and i have a button to make it all disappear but i am having trouble with the script

button = script.Parent
function onClicked()
if button.MouseButton1Click 
then button.Visibility = false -- this only removes the button how do i get it to remove everything else
	end

button.MouseButton1Click:connect(onClicked) 

is there a better way to remove the GUI's and this script doesn't work i don't know why basically all my text labels and etc is withing screengui which is in the startergui..i am stuck on trying to get the welcome page to diappear

First, the property you are looking for is Visible, not Visitbility.

The Visible property makes its GUI and its GUI's descendants invisible. To get the entire Welcome GUI to become invisible, you have to give them a shared Parent.

To do this, start by creating a Frame. Leave the Frame's Position alone, but set its Size to {(1, 0),(1,0)}. Next, sets its BackgroundTransparency to 1.

Put all of the contents of your Welcome GUI within this Frame, and change your script to set the Frame's Visible property to false.
