SUMIF
Returns a conditional sum across a range.
Sample Usage
SUMIF(A1:A10,">20")
SUMIF(A1:A10,"Paid",B1:B10)
Syntax
SUMIF(range, criterion, [sum_range])

range
 The range which is tested againstcriterion
. 
criterion
 The pattern or test to apply torange
.
If
range
contains text to check against,criterion
must be a string.criterion
can contain wildcards including?
to match any single character or*
to match zero or more contiguous characters. To match an actual question mark or asterisk, prefix the character with the tilde (~
) character (i.e.~?
and~*
). A string criterion must be enclosed in quotation marks. Each cell inrange
is then checked againstcriterion
for equality (or match, if wildcards are used). 
If
range
contains numbers to check against,criterion
may be either a string or a number. If a number is provided, each cell inrange
is checked for equality withcriterion
. Otherwise,criterion
may be a string containing a number (which also checks for equality), or a number prefixed with any of the following operators:=
(checks for equality),>
(checks that the range cell value is greater than the criterion value), or<
(checks that the range cell value is less than the criterion value)


sum_range
 The range to be summed, if different fromrange
.
Notes
SUMIF
can only perform conditional sums with a single criterion. To use multiple criteria, use the database functionDSUM
.
