Thanx Jacob!
Nice 2 find u after such a longtime! Was on an official leave actually. Sure
would oblige if u would also answer my question on the programming panel as
"Counting Errors".
Thanx in advance.

Try the array formula
=SUM(IF(A1:A10<"",IF(ISNA(MATCH(A1:A10,B1:B20,0)) ,1,0)))
If this post helps click Yes

I want to check how many of the entries in A1:A10, are not found to be
existing in another list, suppose B1:B20.
Tried out:
=SUMPRODUCT(--(ISNA(VLOOKUP(A1:A10,B1:B20,1,0))))
but failed. What might be the reason? and what might be its solution except
then a helper column?
