So find your records and sort them descending (as you are) then add the following lines to your script (pseudo-script below)
Go to record/Request/page [ by calculation ; 11 ]
Set error capture [ on]
Omit multiple [ by calculation ; Get(FoundCount) -10 ]
... then continue with your report. If this does not assist you, post again and we'll help you through it. :-)
It's perfect, thank you LaRetta.
