I have a form which draws data from a query in which some of the data is in the form of check boxes. In a continuous display in the form, -1s and 0s appear in the place of yes or no, respectively. Using the property menu, I changed the format to display as yes/no. However, the filter will not recognize yes or no, just -1 and 0. How can I make the filter realize that yes= -1 and no=0?
