Problem in data flow into other pages in TDS SAP Script

Hi Gurus,

I have solved all my problems which i had faced through the creation of the TDS Certificate Layout & programs. But blocked with one problem, which is when there are more line items to be printed and which are moved to the second page. Now for Example in my first page if there are 10 line items printed & then moved to the second page only 11 items are printed and again in third page 11 items are printed, where in my page's are wasted when we take a printout. what could be the problem where i am notable to fix. Please Suggest me what can i do to solve this problem.

Regards
