>>>>>I'm selecting two records in a table so I can copy or delete all the records between each of the selected record. My problem comes when the table is indexed. Is there a way to do this? I'm having a problem determining if the second record is before or after the first record. I'm using 5.0a. TIA

I answered my own question. I added the RECNO() to each of the indexes to create a unique condition. Thanks again....
