Thanks Bruce
why you wrote : "it's complicated" ? it's very easy
in advance tabs i add condition when row should end and that's all
i.e :
MAI:MailBoxNumber % 3 = 0 for 3 records in row
in attached picture where change and effect on one of example app
of course if in numbers will be holes (like in firs row) then condition can be little more complicated
and some work with header is necessary - in my case headers are needless
thanks again
