Permissions and deletion
If the underlying iSheet item linked via an iSheet link column is deleted the link text still appears, but when a user clicks the link an error message is shown. Likewise, if a user does not have permission to view the iSheet item linked, they see the link text and can click the link but are presented with the same message.
