Hi Gaizka, thanks for the reply. I have tried to solve the problem as you suggested. - I created two parameters, one for the main report (num_pages_main, java.lang.Integer, default expression: $V{PAGE_NUMBER}) and one for the subreport (num_pages_sub, java.lang.Integer), subreport banner is locate in "summary" band of main report. - By double clicking in the banner (subreport/subreport params menu) I tied num_pages_sub/num_pages_main ("params": num_pages_main and "expression": $P{num_pages_main} ) - I created a variable integer (var_pages_sub) in the subreport and I have the value of the parameter num_pages_sub. Result: In subreport the variable (var_pages_sub) and the parameter num_pages_sub is null. In main report the parameter num_pages_main is rightly not null. The link between the parameters (main report/subreport) is correct because, for example, if imposed in the parameter num_pages_main the default expression: new Integer(1234), then in the subreport correctly 1234 as a result of num_pages_sub and var_pages_sub. Is very strange! I could not even test the last point that you suggested because the parameter is null.

I use to number the pages in the report the variable $V{PAGE_NUMBER}. This is correct in report, but in subreport with $V{PAGE_NUMBER} the pages start again from 1. How do I switch the pages properly, and continue numbering in the subreport correctly?
