Hide a page where data in Section is Null

Hi

I have created a report in Web Intelligence which contains 3 to 4 sections. The report is a reminder letter to Customers, now the problem is that the report is in Page Display format and I am getting few blank pages in the report which I don't want, because when I export this report in PDF format this blank pages come.

Is there any way to Hide the pages where data in the section is Null?

Thanks,
