The syntax is as follows, =dfunction(range to test, column to perform calculation within, criteria list range). for example: =DSUM(A1:H25,6,J1:L4). Names can be used to substitute for Cell References.
The type of Dfunctions available include the "Big Five" DSUM, DCOUNT and (DCOUNTA), DAVERAGE, DMAX and DMIN, These can be used as required. the Criteria List range must include the Field Heading matching the Excel List, and can use the numeric calculators, =, >, <, <>, >=, <=.
