I have a Nintex Form with a few validation rules associated to controls (i.e., if this field is not blank then that field is required, etc.) When I publish it one of two things happens - either the rules will run as expected and the fields will highlight in a red box but then suddenly the form will close or the rules don't run at all and the form closes.
