TypeError: undefined is not a function (near '...$.validate...')

I see this in a few places, at least when I click on the help-ring:

 $.validate({
            form : '#create-form',
            modules : 'date, toggleDisabled',
            disabledFormFilter : '#create-form',
            showErrorDialogs : true
        });

The form tag on that page does have the id of create-form.

Need to investigate and see if we can determine what's causing it. It's been a little while since I looked at this specific bit of code, so I'm sure it's something dumb.

This is using the jQuery form validator at http://www.formvalidator.net
