append query help

[SlowPoke]

I have a table that I want to add a new record to from another table. I'm working on an append query. I have input parameters to select the record I want, but my problem is when I re-run the query I append the same record again. Yes I could not re-enter the same parameters, but I want the DB to keep track of this. I don't want duplicate records in the destination table. Any advise on how to keep this from happening?

create unique index to advoid duplica records.
