I would like to know if it is possible to have a field prevent modification once data is entered into it. If this is possible can you please tell me how to do this. Also is there was way to work that into a privlege set so that only certain individulas have access to change the field that have administrative privleges. I know how to limit editing on the privlege set but i want the rest of the record to be modifiable, just the one field to be not modifialble after data is entered into it. Thanks, Ron

Just set the field to view only all the time and use a script to populate data in the particular field. The script can control whether to allow editing based on the contents of the field.
