We have a form with a couple of data entry fields that are similar, but one is used much more often than the second. Occasionally a value is entered into the second by mistake. Since sometimes it is OK to enter data into this field, I cannot put a validation rule on it to limit what is entered, but I would like to have a warning pop up that says something like "Are you sure you meant to enter data into this field?".
Is there a way to do this?
We're using Access 2003.
Thanks
