Button Scripting Help

[Nitefang]

Hey all - I'm back with another coding question - been all over the site looking at examples of syntax for button scripts - should be easy (and probably is lol) but so far I cant get it to work - I've put a button in my start button mod that opens my socials page, that much works great - but I want it to close again when I press the button a second time - no luck making it work so far...

any help is appreciated
