[jQuery] Jquery Form Plugin issues

[jQuery] Jquery Form Plugin issues


I'm going nuts here, and I think i've been staring at this far too
long. I have done more than one of these in my day, but for some
reason this just isn't working. I'm hoping a fresh set of genius eyes
can help me out here.
Everything has been checked for validation and so on. Doesn't work in
IE or FF. Thanks in advance!
<script type="text/javascript">
$(document).ready(function() {
    var submitoptions = {
target: '#loading'
        };
    $('#e2').submit(function(){
        $(this).ajaxSubmit(submitoptions);
     return false;
    });
});
</script>
<form id="e2" enctype="multipart/form-data" class="photoform"
action="photo_process.php" method="post">
<label>Photo # 2</label><br/>
<input type="file" name="photo"/>
<input type="submit" name="upload" value="Upload" style="width:100px;"/
