If a user can never change the position of Record 4 ahead of Record 3 (as is the case in your example) what purpose does priority serve. If you had said that the outcome you wanted was: Record 1 from 3 to 10 Record 2 from 10 to 20 Record 4 to 30 <-********* Record 3 from 20 (should 15, Destination between record 2 and record 3)) to 40 <-********* Record 5 to 50 Then that would have made sense. Please clarify, the problem domain does matter to the solution. Sean
