Why am I Receiving an Error Message When I Search or Open a Container?

If a custom field has a special character (#,$,%,&, etc.) in it, you might get an error message every time you try to open or search the container that has the custom field in it. Edit the custom field to remove the special characters.

Go into a container that is not giving the error message, go to My Views > Define Views, and open the view that the container giving error messages uses. Edit or remove any custom fields with special characters.
