How to auto-enter data from previous record

[emerywang]

Hi. I have a file of records with account numbers. Whenever a new record is created, it is assigned an account number. What I want to do is, whenever a new record is created, to have the data from a field of the previous record with that account number to be automatically entered.

So for example, if I make a new record with account number 101, I would like the "price" field to auto enter the price data from the previous record with account #101.

Anybody know how to do this? I guess it would involve sorting the records by account number, and grabbing the data from the corresponding field of the previous record. I'm thinking this requires some sort of self join, but can't figure out how to do it.

Thanks.

Nevermind, I figured it out. The lookup function with a self join, sorted by date in descending order did it. Thanks.
