I am creating a form off of two tables, joined in a query, "Conglomerate," which serves as the recordsource for my form. Before I expanded into a second table, I had a combo box at the top of the page to find values based off of what they began to type in. This served as a really easy way for my clients to toggle between the hundreds of records without having to scroll through with their mouse wheel or do a Ctrl>F. However, since I've added a second table and related it to the first, I haven't been able to set up this combo box. Whenever I do, the list comes up in the combo box when I view it in form view, however whenever I select a record form the list, instead of taking me to that record an error message reading "Run-time error 3345: Unknown or Invalid Field Reference [MasteList.Transaction Name] pops up.
