global and local variable

Belle journéeI have a problem to "send" to a variable from the region-body to the region-after 
In the region-body i use some informations and i would like that the header of the page (so a region-after) contains the number of the current object parsed in the body...
but the problem it seems that i'm not able to see when i'm in the region-after a variable initialized in the region-body....
is that true?

Someone can help me?
Thank uuuuuuuuuu
