Datawindow refresh problem in a nested datawindow

I have a nested report with 5 datawindows. There second and fourth datawindows
are being set by RowsCopy function after retrieving the main datawindow. The
others are retrieved. THe problem here is that when printing/displaying the 
datawindow there are lot of blank pages. 
Pl. advise

THanks
