[jQuery] animate error in IE

[Paul Malan]

I'm losing my mind.  This simple little bit of code works a charm in
Firefox and not IE 6/7:

$('#content').animate({className: 'contentNarrow'},1000, function(){
        $('#podContainer:hidden').fadeIn(1000);
        $("#content").load("screens/order.cfm");
});

The JS error is useless, even using Firebug Lite in IE I can't get any
better detail: Invalid argument on line 1, char 1.

I've eliminated any possible errors involving the callback
functionality--the error remains even without a callback at all.

Any way you can help?
