[jQuery] [validate] submit button keeps adding "required field" to the older message


hi,
i'm new to jquery, i'm currently using the validation plugin to
validate my forms.
here's my code
<script src="includes/jquery/jquery.validate.js" type="text/
javascript"></script>
<script src="includes/jquery/cmxforms.js" type="text/javascript"></
script>
<script type="text/javascript">
    $.validator.setDefaults({
        submitHandler: function() { alert("submitted!"); }
    });
    $().ready(function() {
        $("#addrest").validate({
            rules: {
                restname: "required"
            },
            messages: {
                restname: "
<font face=\"Arial\" style=\"font-size: 9pt\" color=
\"#96A26F\">Please enter your Restaurant Name</font>"
            }
        });
    });
    $(document).ready(function() {
     $('#yes').click(function(){
     $('#tr').hide();
     });
     $('#no').click(function(){
     $('#tr').show();
     });
     });
</script>
<form method="post" action="add.php" id="addrest" class="cmxform">
<table border="0" width="100%" cellpadding="3" cellspacing="0"
id="Table6">
            <tr>
                <td valign="top" align="left" style="width: 98px">
                    <font color="#B9A49B" face="Arial" style="font-size: 8pt">
                        <label for="restname">Restaurant Name</label>
                    </font>
                </td>
                <td valign="top" align="left" style="width: 204px">
                    <input type="text" class="required" name="restname" id="restname"
size="35" style="font-size: 8pt; font-family: Arial; color: #56443D;
background-color:#E1D9D5">
                </td>
            </tr>
</table>
</form>
