If you put this code into a prg by itself then run it several times against the table (outside of your app) does it still cause a C5 error?

>or set the forms datasession to private the error no longer happens. I can run the form, close it, and run it again as many times as I want. Where before the second time i ran the form the C0000005 error would happen. I don't know if this will help anyone else with this.
