I have a mess here.  Last month, when I ran into trouble with our inventory worksheets, upon resolution, we were getting a strange error as listed in the title.  However, it was intermittent, and I was not able to reproduce it with any consistency.

However, now, since updating all of the sales tax tables, I am getting this error any time a transaction is created for any customer with a California address.  _We cannot save sales orders, invoices etc, and the error is the same 'Items you have requested in the record have been deleted since you retrieved the form'.
