Trev, are you able to sort out this; or do you have problems still?
=SUMPRODUCT(
--('Pending Sold'!A:A="name"),
--('Pending Sold'!C:C="sold"),
--('Pending Sold'!F:F>=1),
--('Pending Sold'!F:F<=150000),
--(ISNUMBER(SEARCH({"NEW","UNDER"},S:S))))
PS: As Biff mentioned refer the entire column only if really needed.
