I am sure it is the numbers, Excel had 15 digits of precision, any numbers
after that will be truncated

oops-Sorry, you're right..the formula should have been:

SUMIF($A$2:$A$75,"="&B2,$C$2:$C$75) and column B has only 30 rows

Nonetheless, the discussion so far has not answered the original
question..

Another individual here has been slowly reducing the size of the test
fields
and has found that he finally gets correct results at a length of 15.
Fields
of 16 or greater continue to return erroneous results. The fields being
compared are text strings of numbers. that you tested with 100 characters
suggests that my problem is not in the legth of the fields, but somewhere
else.

I'd still like to know if there's a limit tho??

Thanx

It is certainly not typical having a different size of the range you want
have evaluated A1:A30 and the sum range C1:C75, besides it is useless
since
you can't get it to sum beyond C30 anyway. Nevertheless I tested with a
criteria string that had 100 characters without any problems

Thanx Dave, but

No, strings in column A may recur multiple times in Col C.

This is "typical" use for SUMIF() i.e. to combine multiple occurences
into
1 - no?

Could it be that the ranges don't match: 1:30 in column A vs 1:75 in
column C?

Is there a limit on the number of characters that can be used in the
criteria section of a SUMIF()/COUNTIF() function?

Columns A & B consists of strings with a length of 30 to 50
characters.

I get incorrect results when I try to SUMIF($A$1:$A$30, "=" & B2,
$C$1:$C$75) (This formula is copied down so B2 becomes B3;B4;B5...).
Is
this
a SUMIF limit problem or do I need to look elsewhere for the weird
results
I'm getting?

TIA
