am i doing something work i dont think so this is the script

script.Parent.Clicked:Connect(function()
script.Parent.Parent.Visible = false
end)

the hierarchy basically looks like this
gui
uibutton
localscript (inside the script is the script above)

local script is inside of ui button and ui button is inside of gui

also is there a way to not open note pad and open vs code for the script editor

I haven't really tried the polytoria editor but I have tried roblox's editor and I'm pretty sure that over there visible isn't a property of a gui so, you might want to remove the second .Parent in your script

There was an issue with doing .Visible on GUI objects - it's supposed to be a property but it seemingly breaks in scripts. Try setting a UIView's visible to false instead.
