In SharePoint list have column with Choice column with three selections. In another column, simple text field, want user to enter value if selects any of three choices. Have tried various ways to prompt the user to enter a value in the text field--all without success. ArcherFolders=='Select'&&isNullOrEmpty({Self}), my message box contains brief "Enter Subfolder Name".
Most promising was this solution: https://ootbtutorials.com/2016/02/16/validating-or-requiring-fields-on-nintex-forms/ but cannot make work. What am I doing wrong and is there another simple way to get same or better result? Thanks
