I have a form that was created from a table. I have two fields, Date and Week ending date. I would like the week ending date to be automatically calculated when the date is entered in the Date field. Should I have used a query to create the form? I have read the posts and I can't seem to understand how to do this. I am not very good with Access and it has been a while since I worked with it. I would appreciate your help. Thanks!
