In Access 2010 I have a form with many text boxes. I want to validate the data before saving it. I want only integers (0-9) in this box, anything other than (0-9) will bring up a error msgbox. The data will always be a 12 digit part number. I am having a hard time and have been searching for some time now on how to do this. Any help or suggestions will be greatly appreciated. Thank you.
