I got it working, but it wasn't using Header.instanceManager.count.
Header.instanceManager.count seemed to be counting the number of header
rows in the table, not the number of pages it rendered on. When I added
enough table rows to get to 5 pages, it still only counted 1.I used
xfa.host.numPages to itterate throught the pages, now that I know where
the button is stored.It is working great. Thanks for your help.
