I am testing this plugin (in conjunction with another called 'InFieldLabel.js' that merely fades back the label on focus) and am getting a strange effect where only some of the fields validate.
The test page is: http://www.richardbarnfather.co.uk/esu/php/booking_mike.php All fields have a class of 'required' and the email field has additionally the class of 'email'. Leave all fields blank and click Submit and you'll see what I mean. If anyone can shed any light on why this is happening, I would be very grateful.
