Recursively determine parent records?

Hi All, I have recordset that contains a hierarchical representation of records where a record's [parentid] field contains the recid of the record 'above' the current record. A representation might look like this: Recid, parentid, title 1, 0, Top level record 2, 0, Another top level record 3, 1, A record under the top level record 4, 3, Another level 5, 2, A record under the second top level record If I have currently retrieved the record with recid of 4, I want to work out the 'chain' of records that lead back to the top level record it has been created under. In this instance, that chain would look like: 4, 3, Another level 3, 1, A record under the top level record 1, 0, Top level record I'm wondering if anyone can help me work out how to achieve this? Many thanks in advance! Much warmth, Murray <http://www.planetthoughtful.org/> http://www.planetthoughtful.org Building a thoughtful planet, One quirky comment at a time.
