“#button_1” isn't affected by .click() or .hover()

[yanhat]

Probably a rookie mistake, but my \[code\]#button_1\[/code\] ID isn't affected by the \[code\]click()\[/code\] or \[code\]hover()\[/code\] jQuery effects.If someone could take a quick look at my JSFiddle, it would be greatly appreciated.It's probably pretty obvious, but I want \[code\]#button_1\[/code\] to act as every other button. Again, I suspect it's a pretty stupid mistake, something that I've overlooked.
