Hi fred:

when I append blank in Gisum initially
I replace gisum.sessionkey with left(time(),2) + dtos(add_date) + Add_time

when I append blank in gidetail I replace gisum.sessionkey with gidetail.sessionkey
Are you telling me that this is my problem....if so how can
I get around this....I've inherited this. It's driving me a little
crazy.

No...alot!
