You were combining the criteria in single cells. While this could be resolved in formula with first name only it makes for very a complicated and awkward formula. With the inclusions (sometimes) of last name it might be next to impossible.
It is best to keep the criteria separate as in the attached. NEW/USED as column headers and the names as row headers ... column C in the attached.
Note the inclusion of the source sheet name in the formula where applicable. Rather than trying to hand type the formula click on the square icon just above this formula "box". It selects the whole formula without fail. Copy and then paste into the workbook formula bar. Then Ctrl + Shift + Enter.
Array entered.
