[jQuery] validation in IE6

[jQuery] validation in IE6


I am using the validation and forms plgin together like that:
<script type="text/javascript">
$(document).ready(function() {
var options = {
target:'.cfjq_form_target1',
beforeSubmit: function(){
$('.cfjq_form_target1').empty();
$('.loading1').show();
},
success: function() {
$('.loading1').hide();
}
};
$(".cfjq_form1").validate({
errorContainer: $(".messageBox1"),
errorLabelContainer: $(".messageBox1 ul"),
wrapper: "li",
submitHandler: function(form) {
$(form).ajaxSubmit(options);
}
});
});
</script>
IE6 simply tell me that the line
$(".cfjq_form1").validate({
the object to not accept the method.
Any idea
I am using metadata, validation 1.1.1 and jquery 1.2.1
Thanks
