What happnes if you create a Summary Field, set to the 'count' option, and put it in the sub-summary sections of each break?
And this report layout can be created with no body layout part -- just the Sub Summary part so that you see just the sub totals that you specify in your post.
The sub-section breaks are on AUTHOR. This would not work at all. For a particular author we might have two hardcover, thirteen paperback, and four missing. How would those totals be summed over the entire file?
Your response reads like the second part of a message. Which report layout do you refer to?
Do you mean that you want the summary data NOT for the found records? Always for the whole file, no matter what records you find?
Phil means that when you make the listing if all you want to see are the summary fields you mention then you don;t have to list all the books that make up that list - you can remove the body part and just show the summary lines.
Here's a tutorial on summary reports you can take a look at:
At the end of the tutorial several variations are discussed, including the trick of removing the body part of the summary report to get just the subtotals for each category without listing data from each individual record, (Yes, Sorbsbuster and I are describing the same basic type of report, thus my response was intended to read as the second half of his report.).
