I am just starting to convert from A4. I am starting with two sets of screens one for display and one for entry and changes (both tabbed subforms). On calculated fields (just a string of trims) that work right on field rules, don't show up on the modify screens until I go into one of the fields that is part of the calculated field. After I go into one of the fields the calculated field is displayed on the modify screen, but not on the display screen. After exiting A5 and then the next time I go into A5, the calculated field is blank again, and I have to go into one of the fields to get it to redisplay. How do I get them to stay in the modify screens, until I want them changed, and to display and stay in the display screens? Note: There are no entry fields on the display screens.
