Set the first condition: Click the first pop-up menu, choose an option (such as Name, Company, or City), then complete the condition using the other menus or fields that are shown (they vary depending on your choice in the first pop-up menu).
For example, to include contacts who live in San Francisco, choose City from the first pop-up menu and “is” from the second one, then enter San Francisco in the text field. Any contact whose city is San Francisco is automatically included.
