I have a form with a choice field that is set to use the display format "Option buttons". Based on the selection by a user it will hide other form fields on the form. It was working until I updated to the latest version of Nintex Forms 2010 (188.8.131.52). Now The rules are not being applied. I did a test and discovered that the value of the option button is not being changed on the form when the user makes another selection. If I change it back to a drop down, the rule begins working again.
