The only thing I can think of is that at one point, if you look at my screenshots from December 10, you'll see that I had a table open called "Copy of assets". Could my updates be updating the copy instead of the one I'm currently working on?
Only if that table is the form's RecordSource property, or is included in a query which is the form's RecordSource property. So the first place to look is the Data tab of the form's properties sheet, to see what its RecordSource property is. If it’s a query, the property might be the name of a saved query, or the SQL statement of an unsaved query, so if it's the former you'll need to look at the query design to see which table or tables it includes. If in doubt copy the query's SQL statement into a reply here, for us to take a look at.
