GroupLevel.GroupFooter Property (Access)
You can use the GroupFooter property to create a group footer for a selected field or expression in a report. Read/write Boolean.
You can use group headers and footers to label or summarize data in a group of records. For example, if you set the GroupHeader property to Yes for the Categories field, each group of products will begin with its category name.
You can't set or refer to these properties directly in Visual Basic. To create a group header or footer for a field or expression in Visual Basic, use the CreateGroupLevel method.
To set the grouping properties — GroupOn , GroupInterval , and KeepTogether — to other than their default values, you must first set the GroupHeader or GroupFooter property or both to Yes for the selected field or expression.
