The “Operation must use an updateable query.” message follows an attempt to update a table. A search of the internet found that many experience this problem and are as baffled as I on the cause. There are also many who offer solutions. I tried several with no success … until I stumbled onto Doug’s FAQs. Within seconds my problem was solved. All I did was grant USER full access to the directory containing my access mdb file. Thanks for the help Doug. I have added your site to my favorites list.
