In all examples below, ranges for calculation contain the row #6, which is ignored because it contains text.Func_Range; Range1; Criterion1[; Range2; Criterion2][; … ; [Range127; Criterion127]]The logical relation between criteria can be defined as logical AND (conjunction). In other words, if and only if all given criteria are met, a value from the corresponding cell of the given Func_Range is taken into calculation.Func_Range and Range1, Range2... must have the same size, otherwise the function returns err:502 - Invalid argument.Range1 – required argument. It is a range of cells, a name of a named range, or a label of a column or a row, to which the corresponding criterion is to be applied.Criterion1 – required argument. A string expression representing a logical condition or a cell reference to such string expression. The expression can contain text, numbers, regular expressions or wildcards (if enabled in calculation options).Range2 – Optional. Range2 and all the following mean the same as Range1.Criterion2 – Optional. Criterion2 and all the following mean the same as Criterion1.The function can have up to 255 arguments, meaning that you can specify 127 criteria ranges and criteria for them.If a cell contains TRUE, it is treated as 1, if a cell contains FALSE – as 0 (zero).
