I've been using the validation plugin ( http://docs.jquery.com/Plugins/Validation) and its working as expected for input elements, however I've added it to a checkbox, with it set to required, and when you submit the form it displays the validation message twice next to the checkbox... then if you click it, it doesn't go away and if you continue to try and submit the form, it continues to add 2 more required messages appended to the previous ones.

Any ideas if there's something that needs to be done differently for checkboxes?

Thanks!
