If "(Cannot display the item name)" appears in an error message when a user tries to save a record, the user may not have view permission for the field for which an error is detected.
This error cannot be solved by the user who is entering the record data. In this case, the user should ask an app administrator to check the app settings.

App administrators can identify the field that is causing the problem by checking the app's Permissions for Fields settings. For the steps to do so, see below.

1. Click the App Settings icon (the gear-shaped icon at the upper right of the "View" screen), select the App Settings tab, and select Fields under Permissions.
   
   

2. Check the fields for which permissions are set.
   

Make sure the Permissions for Fields settings allow the user who is trying to save a record to view the field in question. Also, as necessary, configure the settings of the field in such a way that the error does not occur when a record is saved.
The following are examples of actions that could solve the error.

Example actions:

• In the Permissions for Fields settings, delete the permission set for the field in question.
• In the Permissions for Fields settings, grant view permission for the field in question to Everyone.
• In the Permissions for Fields settings, add the appropriate user, department, or group and grant view permission for the field in question.

• On the form settings screen, change the settings that are preventing the user from saving the data for the field in question (e.g., the default value, limits on the number of characters, the required field settings).

After taking the actions mentioned above, check whether the user can save the record.
