Unavailable 'page protection' smartforms

Hi all.

I need all parts of a table in a smartforms, be shown in the same page. If I select the table, and select 'Output Options', there is a flag 'Page protection', but it is in display mode, and I can't put it in change mode to mark it. Could you help me? I have marked flag 'Page protection' in Line type, but it keeps toguether the line, but not all the lines of the table.

Thanks a lot.

Marta.
