No, In Knowledge Base, there is a message to show how to make "Page x OF n" in another method..
If you use View for report printing, join all table what you need, add any calculated field such as rowtotal...
Then the following Formula will be very useful for you!!

TotalPage = CEILING(RECCOUNT()/number_of_detail_record_per_page)

Since in most case you seldom change the detail brand height or header height....
The number of detail record per page can be determinated by sample try!!
For example, you found that there is 12 detail record per page..

Then, TotalPage will be CEILING(RECCOUNT()/12)

So, to make "Page x OF n" will be:

[Page ] + alltrim(str(_pageno)) + [ OF ] + Alltrim(Str(CEILING(RECCOUNT()/12)))

The only pre-cause is that when printing last page, it will ask you twice if you simply use :
Where ... MainKey = ?prtMainKey

You can simply set a PUBLIC or Form New Property to do it....
It will work perfectly!!
Moreover, Using View for printing allow you Set Delete ON to skip deleted record,
and thus RECCOUNT() will NOT return wrong value! ^_^;
