SUMIF2
SUMIF2 is similar to
			Microsoft Excel's SUMIF formula. The difference is that in SUMIF2, you can define the
			operator explicitly.  
		Syntax
=SUMIF2(comparison_range,"comparison_operator",comparison_value,
					value_range)
Example
For each value in the first range which matches the comparison value, it sums the equivalent values in the second range.
				Sumif2(a1:a5,"=",1,b1:b5)
			
With this sample data, this formula returns 58: 
 The comparison value specified in the formula is 1. The comparison value is
				in Row 3 and in Row 5 of the first range (A1:A5). The formula sums the equivalent
				values in the second range (B1:B5). That is, 47+11=58.
