How to add current page and total pages of the report to a barcode (to be shown on each page)

[davide.mezzi]

Hi,

We are struggling with adding current page and total pages of the report to the barcode (to be shown on each page):

We generate a big pdf containing various reports, each of these containing different pages.

For example report 1 has 3 pages, report 2 has 5 page report3 has 2 pages, etc...

On each page for all reports we have to add a barcode; the value of the barcode should be calculated depending on the current page and the total page of the report

But we are facing the following problem : the current page and the total page is representing by the same variable $V{PAGE_NUMBER}. To display these 2 values on each pages it's not a problem, we defined 2 fields

containing the variable $V{PAGE_NUMBER} each one with a different evalution time (evaluation time = Now representent the current page and evaluation time = Group represent the total page of the report)

But for calculation the value of the barcode, how can we retrieve both values at the same time, that's to say at the time we want to display the barcode ?
