i have a database that has been working for for over a year. i have a form that is linked to a qry. when the form opens it shows a blank record. when you type in data in any of the fields you get a msgbox "Field cannot be updated". on clicking OK this message box appears another 4 times then the record can be edited as if the message boxes dint appear. whats more strange is that i have approx 40 different backups of this database. Saved as i was developing it. All these databases have the same fault but didnt yesterday. i dont know whats going on? has this happened to anyone before or can anyone help??? please.
