Specific value in the page footer for each subreport?

[spitFire88]

Hi all, does anybody know how can be displayed specific value in the pagefooter for each subreport in iReport? This value depends on the specific subreport. Lets say we have 3 subreports : x, y and z. All the 3 subreports are part of mainreport which has pagefooter. The page footer diplays the current page number and the count of all pages (i dont have a problem with that part of the request) and also some value for the specific page, which is different for each of these 3 subreports . So x subreport should have specific value x in the pagefooter, same is for y and z subreports - specific values y and z. Can you please help me?
Thank you in advance for your help!
