Keith, You said this is for a selection based listbox so the command would be Old([table]field).
I don't use a selection based listboxes if I need heavy validation pre or post saving so I'm not sure how long you can count on modified changes NOT being saved but I am certain OLD will work while you are editing that specific field. I prefer array based listboxes if I need to do a lot of validating or need to be able to cancel extended entry. The problem with starting transactions from an input form in such a way that they are finished by user action (enter or cancel) is everything you 'touch' within the transaction gets locked until the user is done. Which could be a long time.
