dewdo Posted October 17, 2006 Share Posted October 17, 2006 I am trying to sum fields across rows if a specific condition is true, for example if field 1 from row2 = field 1 from row 4 then SUM field 3 from both row1 and row 4. except the query has to be more general since there are hundreds of rows .... thanks.
