Select Work Areas to Calculate 

Use

Select one or more work areas from the Org Unit drop down list on the left panel of the page. When you select an org unit from the drop down list that has work areas associated with it, it is the same as selecting the work areas beneath it individually. Click on a work area to select it. The work area appears in this list once you select it. You can only select a work area once. Remove a work area by clicking on the minus sign (-) button next to the work area.
