Hi Alberto,
your task can be broken down into a number of smaller tasks;
a) know if the user is looking at the "last page".
b) calculate the totals
c) display the totals.
a) Fortunately there is a local variable, loc:nextdisabled, which is set if the user is on the last page of the browse.
b) Since you are calculating the totals over more than just the page, you will need a function to calculate them. Say you were totalling the "size" as represented by one column. Then you could create a local variable say total:size, and populate that with a function. For example;
if loc:NextDisabled
BuildTotal(total:size,total:amount)
end
c) In the "condition" for the total field put
loc:NextDisabled
Cheers
