I'm trying to add a date time stamp to two separate fields on my form. One field is where user enters their Start Time and the other field is where user enters their End Time. I've added 2 text boxes, StartSystemDateTimeLogged and EndSystemDateTimeLogged that I want the system date & time entered automatically when the user enters their Start Time and End Time. I've searched the forum and tried to use every suggestion I found but I can't get this to work. I have all four fields from the form in the same table and the StartSystemDateTimeLogged & EndSystemDateTimeLogged fields are hidden on the form so the user cannot see them. Any suggestions on how to make this work?
