Getting Duplicate Error Messages with JQuery Validation Plugin

I'm a newbie to JQuery and the Validation plugin.

Short Description: I wanted all of my error messages to appear in one div at the top of the form, instead of next to each label. After a little head scratching and net searching, I came up with the following, which works, but the sourceurl: message comes up twice on the validation. I haven't a clue as to why. Any help would be appreciated. Cheers, John

Source Code:

<form name="siteauth" id="siteauth" action="savedata" type="POST">
    <div class="message"></div>
    <fieldset>
        <label>Short Description:</label>
        <br><input id="shortdescription" size="75" type="text" maxlength="50"  name="shortdescription"/>
        <br><label>Source URL:</label>
        <br><input id ="sourceurl" size="75" type="text" maxlength="500"  name="sourceurl"/>
        <br><label>Callback URL:</label>
        <br><input id="callbackurl"  size="75" type="text" maxlength="500" name="callbackurl"/>
        <br><label>Callback Content:</label>
        <br><input id="in4"  size="75" type="text" maxlength="100" name="callbackcontent"/>
        <br>
        <br><input type="submit" value="Add"/>
    </fieldset>
</form>

<script>

    $(document).ready(function(){
        $("#siteauth").validate({
            rules: {
                shortdescription: "required",
                sourceurl: "required"
            },
            messages: {
                shortdescription: "Enter a short description. ",
                sourceurl: "Enter a Source URL. "
            },
            errorElement: "div",
            wrapper: "div class=\"message\"",
            errorPlacement: function (error, element){
                error.appendTo($(".message"));
            }
        });

    });

It's because you gave the class to the wrapper inside your error element as well, so this:

wrapper: "div class=\"message\"",

Should be just:

wrapper: "div",

Then it's not appending it to the top container and the elements it's creating inside there. You can give it a try here.

The above works, but a better solution is to use the intended property, errorLabelContainer, which is also shown/hidden automatically i there are/aren't any errors, like this:

$(function(){
    $("#siteauth").validate({
        rules: {
            shortdescription: "required",
            sourceurl: "required"
        },
        messages: {
            shortdescription: "Enter a short description. ",
            sourceurl: "Enter a Source URL. "
        },
        errorElement: "div",
        wrapper: "div",
        errorLabelContainer: ".message"
    });
});​

Give that version a try here.

Instead of using the class use the ID attribute.
For example <div class="message" id="errmsg"></div> and change the Jquery line into
errorPlacement: function (error, element) { error.appendTo($("#errmsg")); }
