You could create a hash of each row and store the hash value in a hidden field. Then on form submission, hash the current version of the same row, and make sure it matches the hash in the hidden field of the submitted form -- if not, the record changed in between form creation and submission. Actually, rather than creating a separate hidden field, you could even set the record hash as the form's _formkey value (which is what 'detect_record_change' actually does). Anthony
