The logic behind your premise is flawed. If some error then display message Else force save End If Select all Open in new window Looks nice but it doesn't Without backup, your business will fail. I agree if there is no records why would I expect to see anything. You might want to do that because otherwise unless your user understands how to use the esc key to back out of an update, he'll end up in what seems to
