Where are the group titles for each government type, such as those you saw for the Left and Right groups in Figure Where are the aggregate statistics, such as Sum , for each group, as you saw in Figure Click View to return to Design view and scroll down the page.
Take another look at the group sections. Yes, there is a GovtType header a group header above the Detail section, and, yes, there is a GovtType footer a group footer below it. But they're empty—there aren't any controls in them. Here's the nasty little secret about creating groups in the Sorting and Grouping dialog box. It's like building an aquarium. When you create the group in the Sorting and Grouping dialog box, all you've done is buy a tank.
You have got to put water, fish, and a plastic gazebo or two into it to make it into an aquarium. Ignoring the fishy metaphors, you must create the controls—labels, text boxes—to make the groups meaningful and informative.
Fortunately, adding the controls is not hard. Because you now have a government type group, you don't need the GovtType field in the Detail section. You want to identify each group by government type, so you can use the same field in the group header section. Here are the steps:. Are you having trouble moving the text box into the Header section? When you move the pointer to the top of the text box, make sure it changes to an open hand, not the pointing finger.
If you still have trouble, here's an alternative method: Cut the text box, select the group section header bar, paste it, and then position it within the section.
Q1: These exercises are tiresome and tedious. Do you really think it's worth my time to go through all these steps for a report I will never want to create? A1: It's true that you're unlikely to have this exact set of controls and circumstances.
But what you are doing here—changing fonts, resizing labels, moving text boxes—involves typical tasks for editing reports. You'll be able to build on this knowledge base for the design challenges you face.
A great advantage of grouping is including summary statistics for each group. These are usually created in the Group Footer. You've already included summary statistics for the area and population fields in the Report Footer. A little cutting and pasting and some editing will give you the same aggregates for these fields by group:.
One thing immediately strikes the eye: Within each group such as Communist , the country names are not alphabetized. Let's alphabetize them. Now let's take a closer look at the report. At the end of the group, there are now group totals for area and population. The same expressions that calculated total area and population for all of Asia when they were used in the report footer section now calculate the group totals when used in the group footer section.
As for the rest of report, it's adequate, but it could be better. Forcing new pages before each group would give you an improved layout. You can also have the group's name appear again at the top of the next page when the group's records span more than one page.
