[jQuery] validation works in FF, but not in IE??

[jQuery] validation works in FF, but not in IE??


Hi, i use the validation plugin form http://docs.jquery.com/Plugins/Validation
All works perfect, i thought.....
With Firefox it works really perfect, but when i change to explorer
mode, there is no validation at all?
Spent all evening to this problem, but really cant find out why its
not working.
Please can someone help me a bit?
This is the code:
$().ready(function() {
    // validate the form when it is submitted
    $("#commentForm").validate();
    // validate signup form on keyup and submit
    $("#mailForm").validate({
        rules: {
            naam: "required",
            telnr: "required",
            email: {
                required: true,
                email: true
            },
            geslacht:{
                required: true
            },
        },
        messages: {
            naam: "Graag uw naam nog invullen!",
            email: "Graag nog een geldig email adres invullen!",
            telnr:"Graag nog een telefoonnummer invullen!",
            geslacht:"Aanspreek titel nog aanvinken!"
        }
    });
});
And this is the form:
<form class="cmxform" id="mailForm" method="post"
action="bedankt.php">
    <fieldset>
        <legend>Contact formulier</legend>
        


            <label for="uwnaam">Uw naam</label>
            <input id="naam" name="naam" />
        



                


            <label for="email">Email</label>
            <input id="email" name="email" />
        



        


            <label for="telnr">Telefoon nr:</label>
            <input id="tel" name="telnr" />
        



            

<fieldset id="titel">Aanspreektitel:
            <label for="aanspreektitelDhr">
             Dhr. <input type="checkbox" id="dhr" name="geslacht"
value="Dhr.">
            </label>
            <label for="aanspreektitelMw">
                 Mw. <input type="checkbox" id="mw" name="geslacht" value="Mw." >
            </label>
        </fieldset>
