Stuck using Masonry

Hi Guys,
I am trying to implement the masonry plugin on my blog www.Iamvishal.com but I can't seem to get it working.

Below is my code. Any clues as to what I am doing wrong ?

[CODE]
$(window).load(function () {

$('#content').masonry({columnWidth: 185});

});

[/CODE]

Cheers,
vishal
