>>>>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 ran into little problem. The procedure works great when all the records are unique in the index key. If the last record I select has multiple records with the same key past it, it selects those records also. Don't know if you have run into this before. Any suggestion would help. Thanks again.
