Hi, I'm using this mootools javascript snippet to equalize the height of my columns:

window.addEvent('domready', function() 
{
    var columns = $$('.equalize');
    var max_height = 0;

    columns.each(function(item) 
    { max_height = Math.max(max_height, item.getSize().y); });

    columns.setStyle('height', max_height);
});

Problem is it's not working properly on Chrome. It's getting the minimum height of the 2 columns instead of getting the maximum. What seems to be the problem and how do I fix it? Thanks in advance!
