I am using Excel 2007 and am having trouble with certain numbers. The cell formatting is set to general number. When I type in 12-2896 (part number), it gets changed to Jan96. When I check the formatting, it has changed itself to a custom number into a date format. It only does this with a few numbers. If I change the cell to text, it works fine, but I need it to be in number format to interact with my Access 2007 database. Any ideas?
