I've run into a rather strange problem. In Access 2002, I have a Phone Number field (Text) that is meant to store (obviously enough) phone numbers. However, when I enter 2009 as the last four digits (ex. (555)-555-2009) the number is changed to (555)-555-2010. This also occurs if I enter the number directly into the table (which doesn't have an input mask). I have tested it in a new form (even without input mask), and a new table, which both result in the exact same thing. Any ideas?
