I have a rule on my O365 nintex form, the purpose of the rule is to disable few controls when the email address of the person field that I have on the form is different from Current user email address. The rule works fine when there is name in the person field but it generate error when it is empty. This is the formula that I have on the rule isnullorEmpty(Entity Controller(Email))||Entity Controller (Email)!=Current User (Email) . Entity Controller is the name of the field. And attached is the error that gets thrown by the form. Could you advise me how to fix this? Thank you
