smartform - 4th page

Hi all,

I developed a smartform composed by 3 page.

first page with secondary window;

second page with main window;

third page with secondary window;

I add the 4th page, and is print correctly after 3 page.

now the problem is:

I want that the 4th page is print ONLY if the variable wa_var = 'X'.

I add the command line, at the end of 3th page, but there's an error:

new page not allowed in the secondary windows

( in fact in the 3th page there's a secondary window )

any idea ??$

tks a lot,

bye
