I am working in a database used to register students for Cooperative Education at a University. When we register students, we have a form with their information, that contains a subform that contains the actual interview times registration for each student. In the original database (before my time), when you click in the subform to choose a time for a student to interview with a particular company, a table (query?) pops up showing the current times that are already registered for that company to help prevent double booking. I am trying to implement this in our current access database, but I cannot figure out what is making this popup in the original. There is no macro or vba code associated with this as far as I can tell.
Thanks in advance for your help!
