have u tested the formula when there are A-100 rows
of formula results(number,text,error)...?

No. In your original post you didn't say anything about having numbers or
text. Try this array formula**:

A1:A10 = numbers, text, empty cells, formula blanks, error values
B1:B10 = numbers
C1:C10 = text
F1 = a number from 1 to 7, the error.type

=SUM(IF(C1:C10="x",IF(NOT(ISNA(IF(ERROR.TYPE(A1:A1 0)=F1,B1:B10,#N/A))),B1:B10)))

Sir Valko,
thanks, have u tested the formula when there are A-100 rows of formula
results(number,text,error)...?

i tried to test the sp formula just as u told me...yet i dont know why
error.type reads a non-error into an error...is this a circular logic..
formula do not work when i do "error.type(A1:A100)" in sp..

regards,
driller

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.

to summarize the error checking tasks of my co-authorses...

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...

in my formulation list workbook, i have one column filled with
different
formulas...
result can be a text, number, and all sorts of known error
types....e.g.

#NULL!
#DIV/0!
#VALUE!
#REF!
#NAME?
#NUM!
#N/A

I like to count (A1:A100) how many formula are bearing each
error.type...
this may enlighten me how to clean the list of formula bearing
correct
results...

pls. bear with me...
