For my method, you need a unique field that represents the order. This would usually be the PK (autonumber field). If you don't have a PK, then my method won't work
Would have been helpful to know that - does the scanner also populate the weight control? If so, then you probably need to use a different event to populate the values - such as the form before update event.
You have numerous other suggestions, so I'll bow out
Hi KitaYama your suggestion works perfectly thank you. It was initially generating some kind of syntax error but i shut down the database and opened it again and all was fine. Thanks again for taking the time to help and also to everyone who made suggestions....i'm always amazed at the help and support i get from you guys.
