Adding Formula Rows and Columns
Formula rows contain formulas that apply to form rows. Formula columns contain formulas that apply to form columns. For example, you can create a formula column (column D) that computes the percentage variance between the January sales (column A) and February sales (column B). The formula defined for a formula row or column applies to all row or column dimensions. To define or assign existing formulas to forms, select the appropriate row or column on the Layout tab and then display formula building options under Segment Properties (see Creating Formulas).
