Note that “List Price” appears in the "Selected Fields" box after “List Price” was clicked in the “Available Fields Box”.
Once a field is selected (clicked on), it jumps to the “Selected Fields List”. You then repeat the steps until you have selected all the fields you need. You may select as many fields as you like but, when using FMLS, you must include the fields listed on the previous screen.
