Function definition: (Copy & paste into FileMaker's Edit Custom Function window)
No matter where the user scrolled, this function lets you know exactly what rows are visible.
The Objname parameter means you'll need to have a named object in the portal rows. The portal also has to be named.
FileMaker 8.5 required.

Great Custom Function, but I felt the chance for recursion failure due to missing object names really needed an explicit test and escape prior to running recursion. So I added the following lines to my version, perhaps this comment will help anyone else do it without having to re-invent this:
// Test for valid Object names
PatternCount ( LayoutObjectNames ( Get ( FileName ) ; Get ( LayoutName ) ) & ¶ ; objName & ¶ ) <= 0 ; "objName missing" ;
PatternCount ( LayoutObjectNames ( Get ( FileName ) ; Get ( LayoutName ) ) & ¶ ; portalName & ¶ ) <= 0 ; "portalName missing" ;
// Object names Exist, continue
... Continue existing Let () and add and ending ")" to close the above Case.

Doesn't seem to work with FM12, getting a "?"
Worked great with FM11

|if you get a "?" try giving a object within the portal a name, that solved the problem for me on a similar portal Row Count CF|
