But this formula cannot refer to a quantity in a schedule, which is beyond the scope of the calculation.

Another field is COST. Can someone tell me if it is possible to have a formula or expression to multiply QUANTITY times COST to get a total cost for the quantity?<BR /> When I try to do this expression, QUANTITY does not show as an available choice.<BR /> Thx</T></DIV> Mon, 25 Feb 2019 10:48:45 GMT https://community.graphisoft.com/t5/Collaboration-with-other/Elements-schedule-and-total-cost/m-p/288155#M37664 lagodue 2019-02-25T10:48:45Z https://community.graphisoft.com/t5/Collaboration-with-other/Elements-schedule-and-total-cost/m-p/288156#M37665 Unfortunately this is not possible, since the Quantity you are referring to is derived from the number of elements grouped together in an Interactive Schedule, rather than a property or value associated with an individual element. <BR /> <BR /> Expressions can calculate values based on the native properties of a specific element (e.g. length) in combination with other properties or constants (e.g. cost per length unit); thus one can derive the cost of a piece of steel based on the length times the cost per meter or foot.
