In an excel spreadsheet, I established a query, to an Access table. It appears to work fine. And whenever we have updated the datbase, I can refresh the spreadsheet, with the click of a button "!". However whenever I open this file; I get a warning message. And also whenever I save this file; I get another warning message. I have displayed these two messages in the attached file. What are these messages trying to tell me? How serious are they? And how do I resolve them properly?
