SUMPRODUCT won't work on a row
You need to transpose your array:
=SUMPRODUCT(--(A10:U10={"P";"B";"S";"V";"H";"PBSVH"}))
Note the semicolons instead of commas....

The following formula works on a column range (A1:A40), but not on a row
range (A10:U10). What have I missd?
=SUMPRODUCT(--(A10:U10={"P","B","S","V","H","PBSVH"}))
