Thank you dear Tom, for fast reply, but your example:
?_sc=address/&rs:def:_lv:ob=cls_rlog_date_time%20ASC not working (i change address to my db name). The script write this: "Invalid Order By : cls_rlog_date_time". I do everything you wright to me, but no way.

>"Invalid Order By"

This would appear if you forgot to add (sr).
Would you check it again? Also try other fields like "first_name" to
see the problem occurs on others as well as "rlog_edit_date_time"
