Hello everyone. I'm trying to figure out a problem for my work. I'm working in an Access form (DAO) and there is a field called "Target Group" in the database. There are about 40 target groups and the user needs to be able to select any combination/number of them to query the database with. Also, more target groups may be added to the database in the future. The database will be maintained by a person who does not know how to program after I leave. I would like to do this with list boxes since the person who works there after me can add new target groups without using VBA code, but I have no idea how to approach this because it seems too complex for a listbox. Any ideas of how to allow this kind of complex query with such a large number of choices?
