AVERAGEIFS

Designates the cells whose values are averaged. In this case, average-range need not have the same size and shape as cell-range-1 through cell-range-n. The actual cells that are added are determined by using the top, left cell in average-range as the beginning cell, and then including cells that correspond in size and shape to cell-range-1 through cell-range-n. If a cell in average-range is empty, that cell is ignored. Each cell in average-range is used in the average calculation only if all of the corresponding criteria specified are true for that cell.

Designates the first range of cells to be inspected.

selection-criteria-1 specifies the criteria for the first range of cells that will be averaged. In the case of text, selection-criteria-1 can consist of any comparison operator followed by the operand against which each cell's value is to be compared. If a cell in any selection criteria range is empty, it is treated as if its value was 0. Cells that contain TRUE evaluate to  1; cells in any range that contain FALSE evaluate to 0. selection-criteria-1 can include one or more wildcard characters, question mark (?) and asterisk (*). A question mark matches any single character; an asterisk matches any sequence of characters. To search for a question mark, asterisk, or tilde character, prefix that character with a tilde (~).

The optional arguments selection-criteria-2 through selection-criteria-n have corresponding arguments cell-range-2 through cell-range-n, and have the same semantics as selection-criteria-1 and cell-range-1, respectively.
