'''javascript $(document).ready(function(){ $('button').click(function(){ $(this).siblings().removeClass('selected'); $(this).addClass('selected'); }); }); ''' I used siblings() method for $('button').removeClass('selected') in teacher's code. But why this code doesn't work?

I tried it using some HTML and CSS I whipped up for testing it and it seems to work just fine:
<button>one</button>
<button>two</button>
<button>three</button>
.selected { color: red; }
You had the right idea about code formatting but the wrong character. You need three accents (`) not apostrophes ('). And please post the HTML part of the code, I suspect that's where the issue is.
