count instances on page

[Former Community Member]

Hey is it possible to count the number of sub instances on one page.



So page 1 has 3 sub instances..and page 2 has 4 sub instances?



What I am trying to do is get the first and last sub instance on each page. So I know that page 1 has subinstance 0-3...and page 2 has 4-7 etc?



Any idea's on how to get this to work?
