Greetings. I have a many-to-many relationship, where one table contains the parent records (say contractors) and a second contains related child records (say services). The child table is a single table, with a single field listing all the services available. These two tables are joined by the many-to-many table. I have a form with page tabs. I want to insert the services as a sub form, but rather than a continuous form that lists all the services and additions being made via a combo box, I would like to know if it is possible to have check boxes instead? I can then create a new contractor, click the tab and begin checking all the boxes for the corresponding services they offer. These selections will then need to be written to by join table that contains the unique IDs for each contractor and service. Thank you.
