>I have a form that based on a code selected from a combo, input is required in anywhere from 1-6 other fields on the form. I was thinking about making them DISABLED or VISIBLE=.F. depending on what is picked in the combo. Most likely, the control of the other fields needs to be in the InterActiveChange property for the combo. Or should it be in each independent field in some sort of DISPLAY property? What about when data is displayed via the NEXT/PREV controls on the form. Where should I control the fields from in that case? Is there one property that can handle them all.

I would suggest placing the enable/disable code in the REFRESH method of the individual controls. Then during the combo interactivechange you can either call THISFORM.Refresh() or (if it only involves a small number) REFRESH() each control individually.
