I've been working on an inventory form in access and have been having good success so far, but just recently, I've noticed that I am having a hard time having the Master query populate with all the names of the attached tables/queries. I have the Master-tab subform set to Master Query while Site 1 and Site 2 have their own queries. I need any items newly added to Site 1 or Site 2 to be added to the Master Query, but I cannot get it to work. Here are some screenshots.
