I'm creating an Excel file and want to use dual dropdown list. There are 3 sets of info. List of department, list of positions within each team, and list of staff names. First choose the dept, then choose the position, and then it'll list the staff's name from the team. Some department would not have a position listed, but there is a still staff's names listed. Since this would be updated on an as needed basis, I want to setup something that's easy to update.
