Syntax
DVAR(database,field,criteria)
Database is the range of cells that make up the list or database. A database is a list of related data in which rows of related information are records and columns of data are fields. The first row of the list contains labels for each column.
Field indicates which column is used in the function. Field can be given as text with the column label enclosed between double quotation marks, such as "Age" or "Yield," or as a number that represents the position of the column within the list: 1 for the first column, 2 for the second column, and so on.
Criteria is the range of cells that contains the conditions you specify. You can use any range for the criteria argument, as long as it includes at least one column label and at least one cell below the column label for specifying a condition for the column.
