Smartform : Data in main window

Hi,

I have designed a smartform, in which some data is being passed to main window.

In main window I am looping a table to display the data.(Item details in PO)

The layout of smartform is like:

Some windows an logo above main window.

Main window.

And some windows having terms and conditions below main window.

what is happening is : my main window is with height 5cm in smartform layout. So if the height of the data to be displayed in it, is 15cm, its print preview come as,

page 1:

Some windows an logo above main window.

Main window data.(5cm)

windows having terms and conditions below main window.

page 2:

Some windows an logo above main window.

Main window data.( next 5 cm)

windows having terms and conditions below main window.

page 3.

Some windows an logo above main window.

Main window data.(next 5 cm)

windows having terms and conditions below main window.

What I want :

Data should come as:

windows an logo above main window.

Main window data.(Entire data of 15 cm)

windows having terms and conditions below main window.

what to do?? why is this happening even if i am displaying data in main window which supposed to adjust the height depending upon data in it ??

Pls help.
