More than half page blank in each page of report.

I am designing CR for Clinical Laboratory.

I have multiple page footers in Crystal Report. Those are suppressed and Suppress Blank section is also checked.These page footers are conditionally (When TestId= X) un suppressed in my report. (For Example when Test Id=18 Suppress is false for Page Footer1 and similarly for other page footers.)
It is working fine. But report have blank space (more than half ) in bottom of page.

please help me.
