I have 3 tables and in between 2 helptables with many-to-many relationship. I want these tables to be shown in one Form with a grand-master, master and child relationship. grand-master in a listbox, then the other two in datasheet forms. I tried and can only connect between 2 tables and the question is how to connect these 3 tables with the 2 helptables (many-to-many) inbetween in 1 form in order that I click a row in the grand-master I get list in the master and when I click a row in the master, I get the list in the child.
