Your English is not easy to understand. I think this is what you want:

A1:A7 = errors returned by formulas
B1:B7 = numeric values
C1:C7 = names

=SUMPRODUCT(--(ERROR.TYPE(A1:A7)=n),B1:B7,--(C1:C7="name"))

Where n = a number from 1 to 7. See help on ERROR.TYPE for those numbers.

Try SUMIF:

=SUMIF(A1:A7,#DIV/0!,B1:B7)

thanks for ur kind reply,

the purpose actually is to count how many times an error exist in a
formula
whwn multiplied to my column (B1:B100).
Note: Column (B1:B100) contains the number of times a certain cell
formula
from column A had been utilized in the workbook of 2 sheets.

i'm thinking to use sum or sumproduct yet i find hard time for some
error
type counting (e.g. #Ref!, etc)...

Purpose : to distinguish those formulas in the workbook that has to be
revised by my co-authors and by how may times for each author assigned
for
each errot type correction..

thanks if someone will help me other than from my co-authors listed in
column(C1:C100)

been dribled with my regards,
driller

The Error Types return text strings, so a simple COUNTIF should work:

=COUNTIF(A1:A100,"#DIV/0!")
=COUNTIF(A1:A100,"#NAME?")
etc...

HTH,
