I have a database in Access 2007 with a main form and several subforms which function ok. However one of the subforms cannot be accessed by code. In the object browser this subform is not listed but I can find it when I click on the main form. When I click on the subform and then click on it's address I get the message: "Cannot jump to this "address" because it is in the library "address" which is not currently referenced." What is the problem and how can this be corrected?
