I have a list that contains a choice field set as a checkbox. It contains a number of items that need a process applied to them. When the process is complete for an item, it is checked. When the List-item is saved and reopened for further work, only the checked items are in the choice field. I want to be able to edit the list-item and continue checking the choice field until I have checked all the choices. Also, is it possible to generate a %Complete field to show status of the work?
