I'm using an access driver for a Start Date: if a start date is past its modules time-dimensioned end date for that month it should be possible to edit, otherwise not. The boolean for this was created and looks good as it is checked/marked for all up-coming start dates and blank for past ones. But when I select it as "Write Access Driver" all Start Date's vanish apart from those dates that fulfill the DCA criteria. I always want to be able to READ all the Start Dates, no matter what time. I simply wanted future ones to be editable..
