[jQuery] moreSelectors plugin syntax issue?

Hi all,

I'm using the jQuery Form plugin by Mike Alsup and jQuery More Selectors
here: http://www.softwareunity.com/sandbox/JQueryMoreSelectors/

I have a callback function which I'm calling with the following syntax:

    function validate() {
        // ensure something is at least filled out.

        if ($('#form2:modified'))
        {
            $('#error').show("slow", function(){
                setTimeout("$('#error').hide('slow')", 10000);
            });

            // Do not submit the call to server.
            return false;
        }

    }

This seems to error out, and I can't find where the syntax issue is.

Thanks for any help.
