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:
Case (
// 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.
