Update query

J

I have a simple query, but I seem to be having some trouble. My table
consists of over 100,000 records. Each record has a DL field, and I want to
update these records to have another field called DL4 which takes the DL
field truncates it down and inserts those last 4 into the DL4 field. I tried
to run an append query then update the field, but when I do that all it does
is double the number of records in my table. I'm thinking there is something
I'm leaving out. Any help would be great.

Thanks
