[jQuery] [validate] - IE6 Issue

[Up-Works]

$('form#order').validate();
$('input#step2').livequery('click',function() {
                        if($('form#order').valid()) {
                        $('div#stepOne').hide();
                        $('div.step').html('Step<br\/>Two');
                        $('div#stepTwo').show();
                        }
                        return false;
                        });
The if() statement: if($('form#order').valid()) above causes IE6
error:

Object Doesn't Support this Property or Method

Any thoughts?
