I'm new on working with databases. Right now, I'm working on an Access 2013 database. In my table I have first name and last name, the job and other related personal information. I also have three combo box fields (named Fecha Adiest 1, Fecha Adiest 2 and Fecha Adiest 3) that allows you to select the date in which the person will be invited to a training. I have another text box named Fecha Invit which is supposed to be auto filled with the value of the greater date 1, 2 or 3. How can I populate this field?
