It can be done with Frequency and Match
=COUNT(1/FREQUENCY(IF((A1:A100="UK")*(B1:B100<""),MATCH(B1 :B100,B1:B100,0))
,ROW(INDEX(B1:B100,0,0))-ROW(B1)+1))
which as an array formula is committed with Ctrl-Shift-Enter, but the
SUMPRODUCT is easier.
For more conditions, you just add it to the first part, like so
=SUMPRODUCT((A1:A100="UK")*(C1:C100="other
value")/COUNTIF(B1:B100,B1:B100&"")*(B1:B100<""))

Thank you so much - your a top man - did the trick I was messing with
FREQUENCY & MATCH functions which were driving me crazy.
Can I add more than one Criteria eg UK and maybe another coloum criteria?
Thanks

What I need is a formulae that will let me specify if colulm A is UK

the unique names in colum B - the answer should be 2 (Mike & Rose are

UK)
