In general terms, your PL/SQL expression should evaluate to true or false - true will display the region, false will hide it. It's analogous to writing the conditional expression part of an if statement.
So, if you had normal PL/SQL code that looks like this:
if :P999_MYPAGEITEM is null or :P999_MYPAGEITEM = 0 then
end if;The equivalent conditional pl/sql expression would simply be:
   :P999_MYPAGEITEM is null or :P999_MYPAGEITEM = 0 Note: this is NOT the same as you would do for "PL/SQL body returning boolean Expression", which looks more like:
   return :P999_MYPAGEITEM is null or :P999_MYPAGEITEM = 0;or
declare
   bl_retval boolean;
begin
   bl_retval := :P999_MYPAGEITEM is null or :P999_MYPAGEITEM = 0;
   return bl_retval;
end;
